A table is an arrangement of columns and rows used to organize and position data. Tables can be created on Wikipedia pages using special wikitext syntax, and there are many different styles and tricks that can be used to customise them.
Using the toolbar
To automatically insert a table, click or (Insert a table) on the edit toolbar. If "Insert a table" is not on the toolbar follow these directions to add it.
The following text is inserted when Insert a table is clicked:
{| class="wikitable" |- ! Header 1 ! Header 2 ! Header 3 |- | row 1, cell 1 | row 1, cell 2 | row 1, cell 3 |- | row 2, cell 1 | row 2, cell 2 | row 2, cell 3 |}
This code produces the following table:
Header 1 | Header 2 | Header 3 |
---|---|---|
row 1, cell 1 | row 1, cell 2 | row 1, cell 3 |
row 2, cell 1 | row 2, cell 2 | row 2, cell 3 |
The sample text ("Header N" or "row N, cell N") is intended to be replaced with actual data.
Pipe syntax tutorial
Although HTML table syntax also works, special wikicode can be used as a shortcut to create a table. The vertical bar or "pipe" symbol ( |
) codes function exactly the same as HTML table markup, so a knowledge of HTML table code helps understand pipe code. The shortcuts are as follows:
- The entire table is encased with curly brackets and a vertical bar character (a pipe). So use
{|
to begin a table, and|}
to end it. Each one needs to be on its own line:
{| table code goes here |}
- An optional table caption is included with a line starting with a vertical bar and plus sign "
|+
" and the caption after it:
{|
|+ caption
table code goes here
|}
- To start a new table row, type a vertical bar and a hyphen on its own line: "
|-
". The codes for the cells in that row start on the next line.
{| |+ The table's caption |- row code goes here |- next row code goes here |}
- Type the codes for each table cell in the next row, starting with a bar:
{| |+ The table's caption |- | cell code goes here |- | next row cell code goes here | next cell code goes here |}
- Cells can be separated with either a new line and a single bar, a new line and a double bar, or by a double bar "
||
" on the same line. All three produce the same output:
{| |+ The table's caption |- |Cell 1 || Cell 2 || Cell 3 |- |Cell A |Cell B |Cell C |}
- a row of column headings is identified by using "
! scope="col" |
" instead of "|
", and using "!! scope="col" |
" instead of "||
". Header cells typically render differently from regular cells, depending on the browser. They are often rendered in a bold font and centered. Thescope="col"
markup is not technically necessary in wikitables styled with class markup:class="wikitable"
and so on. However, it is easier for other editors to understand the markup when it is present, and the Manual of Style recommends using it because it directly associates headings with corresponding cells, a boon to accessibility.
{|
|+ The table's caption
! scope="col" | Column heading 1
! scope="col" | Column heading 2
! scope="col" | Column heading 3
|-
| Cell 1 || Cell 2 || Cell 3
|-
| Cell A
| Cell B
| Cell C
|}
- the first cell of a row is identified as a row heading by starting the line with "
! scope="row" |
" instead of "|
", and starting subsequent data cells on a new line. Thescope="row"
code, as withscope="col"
, is not technically required in wikitables styled with class markup likeclass="wikitable"
, but it is recommended by the Manual of Style for both accessibility and code readability reasons.
{| |+ The table's caption ! scope="col" | Column heading 1 ! scope="col" | Column heading 2 ! scope="col" | Column heading 3 |- ! scope="row" | Row heading 1 | Cell 2 || Cell 3 |- ! scope="row" | Row heading A | Cell B | Cell C |}
- Optional parameters can modify the behavior of cells, rows, or the entire table. For instance, a border could be added to the table:
{| border="1"
|+ The table's caption
! scope="col" | Column heading 1
! scope="col" | Column heading 2
! scope="col" | Column heading 3
|-
! scope="row" | Row heading 1
| Cell 2 || Cell 3
|-
! scope="row" | Row heading A
| Cell B
| Cell C
|}
The final table would display like this:
Column heading 1 | Column heading 2 | Column heading 3 |
---|---|---|
Row heading 1 | Cell 2 | Cell 3 |
Row heading A | Cell B | Cell C |
If you want narrow one-pixel wide borders around all the cells use this in the top line of the table:
{| border="1" style="border-collapse: collapse;"
Here is the revised table:
Column heading 1 | Column heading 2 | Column heading 3 |
---|---|---|
Row heading 1 | Cell 2 | Cell 3 |
Row heading A | Cell B | Cell C |
The simplest way is to use Wikipedia's external style sheet for tables: class="wikitable"
and so on.
{| border="1" class="wikitable" |+ The table's caption ! Column heading 1 ! Column heading 2 ! Column heading 3 |- ! Row heading 1 | Cell 2 || Cell 3 |- ! Row heading A | Cell B | Cell C |}
It produces this:
Column heading 1 | Column heading 2 | Column heading 3 |
---|---|---|
Row heading 1 | Cell 2 | Cell 3 |
Row heading A | Cell B | Cell C |
The table parameters and cell parameters are the same as in HTML, see http://www.w3.org/TR/html401/struct/tables.html#edef-TABLE and Table (HTML). However, the thead
, tbody
, tfoot
, colgroup
, and col
elements are currently not supported in MediaWiki, as of July 2015[update].
A table can be useful even if none of the cells have content. For example, the background colors of cells can be changed with cell parameters, making the table into a diagram, like meta:Template talk:Square 8x8 pentomino example. An "image" in the form of a table is much more convenient to edit than an uploaded image.
Each row must have the same number of cells as the other rows, so that the number of columns in the table remains consistent. For empty cells, use the non-breaking space
as content to ensure that the cells are displayed.
With colspan
and rowspan
cells can span several columns or rows; see the Mélange example further on. However, this has the disadvantage that sorting does not work properly anymore.
Rendering pipe itself
Cell code that contains a single bar in the text will not render as expected: cell code between the first two single bars, or between a double bar and the first single bar becomes (optional) row formatting code. Any subsequent single bars are treated as part of the text. For example, this code:
{| class="wikitable" |- |format modifier (not displayed) |These all |(including the pipes) |go into |the first cell||second cell |- |format |These all ||format |go into |the second cell |}
produces this table (which is probably not what you expected):
These all |(including the pipes) |go into |the first cell | second cell |
These all | go into |the second cell |
However, the format modifier is useful:
{| class="wikitable" |- | Cell 1 (no modifier—not aligned) |- | style="text-align: right;" | Cell 2 (right aligned) |}
Cell 1 (no modifier—not aligned) |
Cell 2 (right aligned) |
To show a visible pipe in a cell, use {{!}}, <nowiki>|</nowiki>
, |
or |
instead. For example:
{| class="wikitable" |- | One {{!}} Two {{!}} Three {{!}} Four {{!}} Five || Alpha | Bravo | Charlie | Delta | Echo |- | Six {{!}} Seven {{!}} Eight {{!}} Nine {{!}} Ten || India | Juliet | Kilo | Lima | Mike |}
The result is:
Two | Three | Four | Five | Alpha | Bravo | Charlie | Delta | Echo |
Seven | Eight | Nine | Ten | India | Juliet | Kilo | Lima | Mike |
Examples
Simple straightforward tables
Minimalist table
Both of these generate the same output. Choose a style based on the number of cells in each row and the total text inside each cell.
Wiki markup:
{| |- | A | B |- | C | D |}
{| |- | A || B |- | C || D |}
As it appears in a browser (note that there are no borders):
A | B |
C | D |
Multiplication table
Note that in this example class="wikitable"
is used to style the table with Wikipedia's external style sheet for tables. It adds borders, background shading, and bold header text.
Wiki markup:
{| class="wikitable" style="text-align: center; width: 200px; height: 200px;" |+ Multiplication table |- ! × ! 1 ! 2 ! 3 |- ! 1 | 1 || 2 || 3 |- ! 2 | 2 || 4 || 6 |- ! 3 | 3 || 6 || 9 |- ! 4 | 4 || 8 || 12 |- ! 5 | 5 || 10 || 15 |}
As it appears in a browser:
× | 1 | 2 | 3 |
---|---|---|---|
1 | 1 | 2 | 3 |
2 | 2 | 4 | 6 |
3 | 3 | 6 | 9 |
4 | 4 | 8 | 12 |
5 | 5 | 10 | 15 |
Whole table operations
Captions and summaries
Explicit table captions are recommended for data tables as a best practice; the Wikipedia Manual of Style considers them a high priority for accessibility reasons, as a caption is explicitly associated with the table, unlike a normal wikitext heading or introductory sentence. A caption is provided with the |+
markup, similar to a table row (|-
), but it does not contain any cells, and is not within the table border. Captions are always displayed, appearing as a title centered (in most browsers), above the table. A caption can be styled (with inline, not block, CSS), and may include wikilinks, reference citations, etc.
A summary provides an overview of the data of a table for text and audio browsers, and does not normally display in graphical browsers. The summary is a synopsis of content, and does not repeat the caption text; think of it as analogous to an image's alt
description. A summary is added with summary="Summary text here."
, on the same line as the {|
that opened the table, along with any class=
and other parameters for the table as a whole. The summary cannot be styled, wikilinked, or otherwise marked up, but must be simple, plain text. It cannot even include italics. (It may contain character entity codes, such as –
.)
Wiki markup example showing left-aligned caption with a source citation, and a summary re-presenting the table data in plain text:
{| class="wikitable" summary="2014 – Africa: 2,300; Americas: 8,950; Asia & Pacific (highlighted): 9,325; Europe: 4,200. 2015 – Africa: 2,725:; Americas (highlighted): 9,200; Asia & Pacific: 8,850; Europe: 4,775." |+ style="text-align: left;" | Data reported for 2014–2015, by region<ref name="Garcia 2005" /> |- ! scope="col" | Year !! scope="col" | Africa !! scope="col" | Americas !! scope="col" | Asia & Pacific !! scope="col" | Europe |- ! scope="row" | 2014 | 2,300 || 8,950 || ''9,325'' || 4,200 |- ! scope="row" | 2015 | 2,725 || ''9,200'' || 8,850 || 4,775 |}
As it appears in a browser:
Year | Africa | Americas | Asia & Pacific | Europe |
---|---|---|---|---|
2014 | 2,300 | 8,950 | 9,325 | 4,200 |
2015 | 2,725 | 9,200 | 8,850 | 4,775 |
Width, height
The width and height of the whole table can be specified, as well as the height of a row. To specify the width of a column one can specify the width of an arbitrary cell in it. If the width is not specified for all columns, and/or the height is not specified for all rows, then there is some ambiguity, and the result depends on the browser.
Wiki markup:
{| style="width: 60%; height: 200px;" border="1" |- | top-left-cell || top-center-cell || top-right-cell |- style="height: 100px;" | middle-left-cell || style="width: 200px;" | middle-center-cell || middle-right-cell |- | bottom-left-cell || bottom-center-cell || bottom-right-cell |}
As it appears in a browser:
top-left-cell | top-center-cell | top-right-cell |
middle-left-cell | middle-center-cell | middle-right-cell |
bottom-left-cell | bottom-center-cell | bottom-right-cell |
Setting borders
Table borders default to a complex shaded double-line (the default in HTML); however, those borders can be set to a thin solid line by using a style-parameter (style="border: 1px solid darkgray;"
), as in the following (Note: if you intend to use the cellpadding
or cellspacing
options along with a border, you must use this format):
Wiki markup:
{| style="border-spacing: 2px; border: 1px solid darkgray;" ! style="width: 140px;" | Left ! style="width: 150px;" | Middle ! style="width: 130px;" | Right |- border="0" | [[File:StarIconBronze.png|120px]] | [[File:StarIconGold.png|120px|Caption when mouse-over image]] | [[File:StarIconGreen.png|120px|Green stellar icon]] |- style="text-align: center;" | Bronze star || Gold star || Green star |}
Note the bottom-row texts are centered by style="text-align: center;"
while star-images were not centered.
Left | Middle | Right |
---|---|---|
Bronze star | Gold star | Green star |
As long as the File:
specs omit the parameter |thumb
they don't show the caption lines in the table (only during mouse-over). The border color darkgray
matches typical tables or infoboxes in articles; however, it could be any color name (as in style="border: 1px solid darkgreen;"
) or use a hex-color (such as: #DDCCBB
).
A column format-specifier (enclosed in |
...|
) can have a style-parameter to set borders on each cell, as follows:
Wiki markup:
{| style="border-spacing: 2px; border: 1px solid darkgray;" ! style="width: 140px;" | Left ! style="width: 150px;" | Middle ! style="width: 130px;" | Right |- border="0" |- style="text-align: center;" | style="border: 1px solid blue;"| [[File:StarIconBronze.png|120px]] | style="border: 1px solid #777777;"| [[File:StarIconGold.png|120px|Caption when mouse-over image]] | style="border: 1px solid #22AA55;"|<!--greenish border--> [[File:StarIconGreen.png|120px|Green stellar icon]] |- style="text-align: center;" |Bronze star || Gold star || Green star |}
Note only the image cells, here, have individual borders, not the text.
Left | Middle | Right |
---|---|---|
Bronze star | Gold star | Green star |
The lower hex-colors (such as: #616161
) are closer to black. Typically, all borders in a table would be one specific color.
Positioning
You can position the entire table, the contents of a row, and the contents of a cell, but not with a single parameter for all the contents of the table. See m:Template talk:Table demo.
Prior to April 2009, using float
to position a table was discouraged; however, it no longer always breaks page rendering at large font sizes. See a floated image, below, under "Floating images in the center".
Floating table
Two table classes floatleft
and floatright
(case sensitive) help floating the table and adjusting table margins so that they do not stick to the text. floatleft
floats the table to the left and adjusts right margin. floatright
does the opposite. Example:
This paragraph is before the table. The text in column 2 spans both rows because of format specifier "rowspan=2" so there is no coding for "Col 2" in the 2nd row, just Col 1 and Col 3. {| class="wikitable floatright" | Col 1, row 1 | rowspan="2" | Col 2, row 1 (and 2) | Col 3, row 1 |- | Col 1, row 2 | Col 3, row 2 |} {| class="wikitable floatleft" | Col 1, row 1 | rowspan="2" | Col 2, row 1 (and 2) | Col 3, row 1 |- | Col 1, row 2 | Col 3, row 2 |} Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam eaque ipsa, quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt, explicabo.

As it appears in a browser:
This paragraph is before the table. The text in column 2 spans both rows because of format specifier "rowspan=2" so there is no coding for "Col 2" in the 2nd row, just Col 1 and Col 3.
Col 1, row 1 | Col 2, row 1 (and 2) | Col 3, row 1 |
Col 1, row 2 | Col 3, row 2 |
Col 1, row 1 | Col 2, row 1 (and 2) | Col 3, row 1 |
Col 1, row 2 | Col 3, row 2 |
Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam eaque ipsa, quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt, explicabo.

Quis autem vel eum iure reprehenderit, qui in ea voluptate velit esse, quam nihil molestiae consequatur, vel illum, qui dolorem eum fugiat, quo voluptas nulla pariatur?
Note that although there are other ways to float a table, such as style="float:left;"
, style="float:right;"
, the only parameters that allow you to position the table under a floated multimedia object are floatleft
and floatright
. For example:
Aligning the table with floatleft
produces:
Col 1, row 1 | Col 2, row 1 (and 2) | Col 3, row 1 |
Col 1, row 2 | Col 3, row 2 |
Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam eaque ipsa, quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt, explicabo. Nemo enim ipsam voluptatem, quia voluptas sit, aspernatur aut odit aut fugit, sed quia consequuntur magni dolores eos, qui ratione voluptatem sequi nesciunt, neque porro quisquam est, qui dolorem ipsum, quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt, ut labore et dolore magnam aliquam quaerat voluptatem. Ut enim ad minima veniam, quis nostrum exercitationem ullam corporis suscipit laboriosam, nisi ut aliquid ex ea commodi consequatur? Quis autem vel eum iure reprehenderit, qui in ea voluptate velit esse, quam nihil molestiae consequatur, vel illum, qui dolorem eum fugiat, quo voluptas nulla pariatur?
But aligning it with style="float:left;"
produces:
Col 1, row 1 | Col 2, row 1 (and 2) | Col 3, row 1 |
Col 1, row 2 | Col 3, row 2 |
Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam eaque ipsa, quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt, explicabo. Nemo enim ipsam voluptatem, quia voluptas sit, aspernatur aut odit aut fugit, sed quia consequuntur magni dolores eos, qui ratione voluptatem sequi nesciunt, neque porro quisquam est, qui dolorem ipsum, quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt, ut labore et dolore magnam aliquam quaerat voluptatem. Ut enim ad minima veniam, quis nostrum exercitationem ullam corporis suscipit laboriosam, nisi ut aliquid ex ea commodi consequatur? Quis autem vel eum iure reprehenderit, qui in ea voluptate velit esse, quam nihil molestiae consequatur, vel illum, qui dolorem eum fugiat, quo voluptas nulla pariatur?
Centering tables
Centered tables can be achieved, but they don't "float"; that is to say, no text appears to either side. The trick is {| style="margin: 1em auto 1em auto;"
Wiki markup:
Text before table... {| class="wikitable" style="margin: 1em auto 1em auto;" |+ '''Cells left-aligned, table centered''' ! scope="col" | Duis ! scope="col" | aute ! scope="col" | irure |- | dolor || in reprehenderit || in voluptate velit |- | esse cillum dolore || eu fugiat nulla || pariatur. |} ...text after table
As it appears in a browser:
Text before table...
Duis | aute | irure |
---|---|---|
dolor | in reprehenderit | in voluptate velit |
esse cillum dolore | eu fugiat nulla | pariatur. |
...text after table
Nested tables
Seven different (blue) tables are shown nested inside the cells of a table. Automatically, the two tables |A| and |B|B| are vertically aligned instead of the usual side-by-side of text characters in a cell. And float
is used to fix each of tables |C| and |D| to their own position within one cell of the table. This may be used for charts and schematics, though as noted above, this is deprecated. Nested tables must start on a new line.
Wiki markup
{| style="border-width: 2px; background: #ABCDEF;" <!-- The nested table must be on a new line -->
| NESTED
|-
| TABLE
|}
| style="vertical-align: bottom;"| the original table again
| style="width: 100px;" |
{| style="border-width: 2px; background: #ABCDEF;"
| A
|}
{| style="border-width: 2px; background: #ABCDEF;"
| B || B
|}
| style="width: 50px;" |
{| style="border-width: 2px; background: #ABCDEF; float:left;"
| C
|}
{| style="border-width: 2px; background: #ABCDEF; float: right;"
| D
|}
As it appears in a browser:
α | cell2
|
the original table again |
|
|
Scrolling
The whole table can be placed within a scrolling list so that new table lines appear on the screen as old table lines disappear. Although MOS:SCROLL disfavors scrolling tables in article space because article content should be accessible on a variety of devices whereas a scrolling table hides some text, a scrolling table may be used in other Wikipedia namespaces.
Wiki markup:
<div style="width: 75%; height: 10em; overflow: auto; border: 2px solid #088;"> {| style="width: 75%; height: 200px;" border="1" |- | abc || def || ghi |- style="height: 100px;" | jkl || style="width: 200px;" | mno || pqr |- | stu || vwx || yz |} </div>
As it appears in a browser:
abc | def | ghi |
jkl | mno | pqr |
stu | vwx | yz |
Color; scope of parameters
Two ways of specifying color of text and background for a single cell are as follows:
Wiki markup:
{| |- | style="background: red; color: white;" | abc | def | style="background: red;"| <span style="color: white;"> ghi </span> | jkl |}
As it appears in a browser:
abc | def | ghi | jkl |
Like other parameters, colors can also be specified for a whole row or the whole table; parameters for a row override the value for the table, and those for a cell override those for a row. (Note that there is no easy way to specify a color for a whole column—each cell in the column must be individually specified. Tools can make it easier.)
Wiki markup:
{| style="background: yellow; color: green;" |- | stu || style="background: silver;" | vwx || yz |- style="background: red; color: white" | stu || style="background: silver;" | vwx || yz |- | stu || style="background: silver;" | vwx || yz |}
As it appears in a browser:
stu | vwx | yz |
stu | vwx | yz |
stu | vwx | yz |
To make the table blend in with the background, use style="background: none;"
or style="background: transparent;"
. (Warning: style="background: inherit;"
, does not work with some older browsers, including IE6, so ensure that the table will be intelligible if the coloring preference fails.)
To force a cell to match one of the default colors of the class="wikitable"
template, use style="background: #f2f2f2;"
for the darker header, and style="background: #f9f9f9;"
for the lighter body.
See: Wikipedia:Manual of Style/Tables, Wikipedia:Background color, list of colors, Web colors and Template:Coltit.

Setting cell parameters
At the start of a cell, add your parameter followed by a single pipe. For example width="300"|
sets that cell to a width of 300 pixels. To set more than one parameter, leave a space between each one.
Wiki markup:
{| style="color: white;" |- | style="background: red;"|cell1 || style="width: 300px; background: blue;"|cell2 | style="background: green;"|cell3 |}
As it appears in a browser:

Vertical alignment in cells
By default, data in tables is vertically centrally aligned, which results in odd-looking layouts like this:
Row heading | A longer piece of text. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. | short text |
---|---|---|
Row heading | Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. Imagine someone scrolling down the page, seeing the tops of "empty" columns, and wondering why they're empty. Use valign=top to align text at the top of columns.
|
short text |
To fix this, apply the valign="top"
attribute to the rows (unfortunately, it seems to be necessary to apply this individually to every single row).
Wiki markup:
{| border="1" cellpadding="2" width="400" |- valign="top" ! scope="row" width="10%" | Row heading | width="70%" | A longer piece of text. Lorem ipsum... | width="20%" | short text |- valign="top" ! scope="row" | Row heading | Excepteur sint occaecat... | short text |}

Cell content indenting
The contents of a cell can be indented using a CSS style of padding-left
.
Wiki markup:
{| style="border-width: 1px; padding: 2px;" |- | Cell content that is not indented || 1 |- | style="padding-left: 2em;" | Indented content || 2 |}
Cell content that is not indented | 1 |
Indented content | 2 |

Setting column widths
To force column widths to specific requirements, rather than accepting the width of the widest text element in a column's cells, follow this example. Note that wrap-around of text is forced.
Wiki markup:
{| border="1" cellpadding="2" ! scope="col" width="50px" | Name ! scope="col" width="225px" | Effect ! scope="col" width="225px" | Games found in |- | Poké Ball || Regular Poké Ball || All versions |- | Great Ball || Better than a Poké Ball || All versions |}
Name | Effect | Games found in |
---|---|---|
Poké Ball | Regular Poké Ball | All versions |
Great Ball | Better than a Poké Ball | All versions |
To set column widths in a table without headers, specify the width in the first cell for each column.
Wiki markup:
{| border="1" cellpadding="2" |- | width="100pt" | This column is 100 points wide | width="200pt" | This column is 200 points wide | width="300pt" | This column is 300 points wide |- | blah || blih || bluh |}
This column is 100 points wide | This column is 200 points wide | This column is 300 points wide |
blah | blih | bluh |
You can also use percentages, such as to equalize the widths of a two-column table by setting one of them to style="width: 50%;"
(or width="50%"
).
One application of setting the widths is aligning columns of consecutive tables. The following are separate tables, with columns set to 350px and 225px. Warning: Setting specific pixel sizes is deprecated, as it interferes with the ability of the browser to adjust content to suit the browser window, device size, user-end font size limits, and other constraints. It is strongly preferred to use relative sizes, in percentage or em values.
Country | Capital |
---|---|
The Netherlands | Amsterdam |
Country | Capital |
---|---|
France | Paris |
Nowrap
In a table that spans the entire width of a page, cells narrower than the widest cell tend to wrap. To keep an entire column from wrapping, use style=white-space: nowrap;
in a non-header cell on the longest/widest cell to affect the entire column.

More complex examples
Mélange
Note: This example is not accessible, and should be avoided as much as possible. For example, nested tables (tables inside tables) should be separated into distinct tables when possible.
Here is a more advanced example, showing some more options available for making up tables. Note however that when |colspan=
is used outside of headers, sorting does not work properly anymore.
Users can play with these settings in their own table to see what effect they have. Not all of these techniques may be appropriate in all cases; just because colored backgrounds can be added, for example, does not mean it is always a good idea. Try to keep the markup in tables relatively simple—remember, other people are going to be editing the article too! This example should give an idea of what is possible, though.
Wiki markup:
Text before centered table... {| border="1" cellpadding="5" cellspacing="0" align="center" |+ '''An example table''' |- ! style="background: #efefef;" | First header ! colspan="2" style="background: #ffdead;" | Second header |- | upper left | upper middle | rowspan="2" style="border-bottom: 3px solid grey;" valign="top" | right side |- | style="border-bottom: 3px solid grey;" | lower left | style="border-bottom: 3px solid grey;" | lower middle |- | colspan="3" align="center" | Text before a nested table... {| border="0" |+ ''A table in a table'' |- | align="center" width="150" | [[File:Wiki.png]] | align="center" width="150" | [[File:Wiki.png]] |- | align="center" colspan="2" style="border-top: 1px solid red;<!-- --> border-right: 1px solid red; border-bottom: 2px solid red;<!-- --> border-left: 1px solid red;" | Two Wikipedia logos |} ...text after a nested table |} ...text after centered table

Floating images in the center
A table can be used to wrap an image, so that the table can float towards the center of the page (such as using: style="float: right;"). However, the table margins, border and font-size must be precisely set to match a typical image display. The File-spec parameter |thumb
(although auto-thumbnailing to user-preference width) forces a wide left-margin that squeezes the nearby text, so the parameter |center
can be added to suppress the left-margin padding. However, |center
sometimes shoves the caption to a 2nd line (under a centered box "[]"), so |thumb
could be omitted and just hard-code the image size, adding a gray (#BBB) border. Using precise parameters to match other images, a floating-image table can be coded as follows:
{| style="float: right; border: 1px solid #BBB; margin: .46em 0 0 .2em;" |- style="font-size: 86%;" | valign="top" |[[File:DuraEuropos-TempleOfBel.jpg|180px]]<!-- --><br /> Temple of [[Bel (mythology)|Bel]] (floating). |}
The text inside the floating table is sized by style="font-size: 86%;"
. That floating-image table floats a typical image box, but allows adjusting the left-hand margin of the image (see temple-example floating below).
Infobox A | |
---|---|
This sample infobox shows how the floating image box aligns toward the center. |
Temple of Bel (floating). |
The caption text can be omitted, or remove the parameter "thumb|" so the caption is hidden until "mouse-over display". Unfortunately the parameter |thumb
(used for displaying the caption) also controls the auto-thumbnailing to re-size images by user-preferences size. To have auto-thumbnail sizing while also concealing the caption, use |frameless|right
instead of |thumb
.
An image set with parameter |left
has a wide right-side margin (opposite margin of parameter |right
), so floating toward the left can be achieved with an image set as |center
inside a table with style="float:left; margin:0.46em 0.2em;".
Recall that, outside an image-table, the parameter |right
causes an image to align (either) above or below an infobox, but would not float alongside the infobox.
Note the order of precedence: first come infoboxes or images using |right
, then come the floating tables, and lastly, any text wraps that can still fit. If the first word of the text is too long, no text will fit to complete the left-hand side, so beware creating a "ragged left margin" when not enough space remains for text to fit alongside floating tables.
If multiple single-image tables are stacked, they float to align across the page, depending on page width. The text squeezes to allow as many floating tables as can fit, as auto-aligned, then wrap whatever text can still fit at the left-hand side.
...by float: right |
...images wrap... |
All these... |
That auto-aligning feature can be used to create a "floating gallery" of images: a set of 20 floating tables wrap (backward, right-to-left), as if each table were a word of text to wrap across and down the page. To wrap in the typical direction (wrapping left-to-right) define all those floating tables, instead, as left-side tables using the top parameter <codee>style="float:left; margin:0.46em 0.2em;". Multiple floating images empower more flexible typesetting of images around the text.
Combined use of COLSPAN and ROWSPAN
Wiki markup:
{| border="1" cellpadding="5" cellspacing="0" |- | Column 1 || Column 2 || Column 3 |- | rowspan="2" | A | colspan="2" style="text-align: center;" | B |- | C <!-- column 1 occupied by cell A --> | D |- | E | rowspan="2" colspan="2" style="text-align: center;" |F |- | G <!-- column 2+3 occupied by cell F --> |- | colspan="3" style="text-align: center;" | H |}
As it appears in a browser:
Column 1 | Column 2 | Column 3 |
A | B | |
C | D | |
E | F | |
G | ||
H |
Note that using rowspan="2"
for cell G combined with rowspan="3"
for cell F to get another row below G and F won't work, because all (implicit) cells would be empty.
Likewise complete columns are not displayed if all their cells are empty. Borders between non-empty and empty cells might be also not displayed (depending on the browser), use
to fill an empty cell with dummy content.
Below is the same table with the order of the declared rows and cells shown in parentheses. The used rowspan
and colspan
are also shown.
Column 1 (row 1 cell 1) |
Column 2 (row 1 cell 2) |
Column 3 (row 1 cell 3) |
A (row 2 cell 1) rowspan="2"
|
B (row 2 cell 2) colspan="2"
| |
C (row 3 cell 1) |
D (row 3 cell 2) | |
E (row 4 cell 1) |
F (row 4 cell 2) rowspan="2" colspan="2"
| |
G (row 5 cell 1) | ||
H (row 6 cell 1) colspan="3"
|
Note that although cell C is in column 2, C is the 1st cell declared in row 3, because column 1 is occupied by cell A which was declared in row 2. Cell G is the only cell declared in row 5, because cell F occupies the other columns but was declared in row 4.
Workarounds
Decimal point alignment
The following is a method to get columns of numbers aligned at the decimal point.
Wiki markup:
{| cellpadding="0" cellspacing="0" | align="right" | 432 || .1 |- | align="right" | 43 || .21 |- | align="right" | 4 || .321 |}
As it appears in a browser:
432 | .1 |
43 | .21 |
4 | .321 |
If the column of numbers appears in a table with cell padding or cell spacing, you can still align the decimal points without an unsightly gap in the middle. Embed a table in each number's cell and specify its column widths. Make the embedded tables' column widths the same for each cell in the column. If decimal points are still misaligned using this method, the main table's column may be too narrow. Add a parameter to increase the column's width. Note: This examples uses some deprecated markup, forcing specific pixel widths with px
, instead of using relative sizing with %
or em
units.)
Wiki markup:
{| border="1" cellpadding="4" cellspacing="2" | {| cellpadding="0" cellspacing="0" style="width: 100px;" | style="text-align: right; width: 50%;" | 432 || width="50%" | .1 |} |- | {| cellpadding="0" cellspacing="0" style="width: 100px;" | style="text-align: right; width: 50%;" | 43 || width="50%" | .21 |} |- | {| cellpadding="0" cellspacing="0" style="width: 100px;" | style="text-align: right; width: 50%;" | 4 || width="50%" | .321 |} |}
As it appears in a browser:
| ||
| ||
|
In the case of preformatted text, you can dispense with the table feature entirely and simply start the lines with a space, and put spaces to position the numbers:
Wiki markup (just spaces!):
432.1 43.21 4.321
As it appears in a browser:
432.1 43.21 4.321
However, there should be a good reason to use pre-formatted text in an article.
Centering tables
See: Whole table operations|Centering tables
Classes
There are several other CSS classes, besides the basic class="wikitable"</class>, documented above.
In the first line of table code, after the
{|
, instead of specifying a style directly, you can also specify a CSS class, which may be used to apply styles. The style for this class can be specified in various ways:
- in the software itself, per skin (for example the class sortable)
- collectively for all users of one wiki in MediaWiki:Common.css (for example, on this and some other projects there is or was the class wikitable, later moved to shared.css)
- separately per skin in MediaWiki:Monobook.css etc.
- individually on one wiki in a user subpage
- individually, but jointly for tables of the class concerned on all web pages, on the local computer of the user.
Instead of remembering table parameters, you just include an appropriate class after the {|
. This helps keep table formatting consistent, and can allow a single change to the class to fix a problem or enhance the look of all the tables that are using it at once. For instance, this:
{| cellpadding="2"
|+ Multiplication table
|-
! scope="col" | ×

simply by replacing inline CSS for the table by class="wikitable"
. This is because the wikitable
class in MediaWiki:Common.css contains a number of table.wikitable
CSS style rules. These are all applied at once when you mark a table with the class. You can then add additional style rules if desired. These override the class's rules, allowing you to use the class style as a base and build up on it:
Wiki markup
{| class="wikitable" style="font-style: italic; font-size: 120%; border: 3px dashed red;"
|+ Multiplication table

Notice that the table retains the gray background of the wikitable
class, and the headers are still bold and centered. But now the text formatting has been overridden by the local style=
statement; all of the text in the table has been made italic and 120% normal size, and the wikitable border has been replaced by the red dashed border.
Collapsible tables
Classes can also be used to collapse tables, so they are hidden by default. Use the class collapsible
to enable collapsing behaviour. Collapsible tables can be sortable, too, by also including the sortable
class; see #Sortable tables. By default, a collapsible table begins expanded. To change this, include the additional class collapsed
. Alternatively, you can use autocollapse
, instead of collapsed
which will automatically collapse the table if three or more collapsible tables are present. You must include a header row, which is where this generated "[hide]" / "[show]" option displays. Example:
{| class="wikitable collapsible autocollapse"
|-
! Header
|-
| Content that starts hidden
|-
| more hidden content
|}
Gives:
Header
Content that starts hidden
more hidden content
Old class mw-collapsible
Another (now deprecated) way, introduced in MediaWiki 1.19rc1, is to add the class mw-collapsible
and optionally mw-collapsed
(see test case at testwiki:User:Krinkle/CollapsingTestpageMw). These classes should be replaced by collapsible
and collapsed
, respectively, any time they are encountered on Wikipedia.
Sortable tables
Tables can be made sortable by adding the CSS sortable
; for details see Help:Sorting. Since this can be very useful, it is wise to keep the possibilities and limitations of this feature in mind when designing a table. For example:
- Do not divide a table into sections by subheaders spanning several rows. Instead, an extra column can be made showing the content of these headers on each row, in a short form.
- Do not have elements spanning several columns; instead, again, repeat the content on each row, in a short form.
- In a column of numbers, do not put text such as "ca." or "approx." before or after a number—it will break numerical sorting. Do not put any text or alphabetical characters in any cell of a column to be sorted numerically. Try not to put a range of numbers (it does not affect the sorting position for numeric sorting mode, and in the case of a range, the first number determines the position, but if, possibly after sorting this or another column, the element is at the top, it induces alphabetic sorting mode). Instead, put these texts in a separate column. Alternatively, for the greatest flexibility, alphabetic sorting mode with hidden sortkeys can be used.
A long form of abbreviated content can be put as legend outside the table.

Sorting and collapsing
It is possible to collapse a sortable table. To do so, you need to use the code {| class="wikitable sortable collapsible"
. Taking the above table and making it collapsible gives you this:

If you want the table to default to collapsed state, use the code {| class="wikitable sortable collapsible collapsed"
in place of {| class="wikitable sortable collapsible"
.
Cells spanning multiple rows or columns
It is possible to create cells that stretch over two or more columns. For this, one uses |colspan=n | content
.
Similar, one can create cells that stretch over two or more rows. This requires |rowspan=m | content
. In the table code, one must leave out the cells that are covered by such a span. The resulting column- and row-counting must fit.

spans two columns. Note that, in the next column, a cell expected to contain "BB" does not exist.
Similar: in the code, cell | rowspan=2 | BBB
spans two rows. A cell expected to contain "BBBB" does not exist.
Section link or map link to a row anchor
To enable a section link's anchor (or a map link's anchor), referencing a specific row within a table, an id="section link anchor name"
parameter needs to be added to the row start |-
or <tr>
:
|- id="section link anchor name"
<tr id="section link anchor name">
Note that each anchor link anchor name must be different from every other in the page (this includes heading names), to create valid XHTML and allow proper linking.
- Example of a map link to a row
When a country label, containing a link, is clicked on the map, the link coded, for example, as [[#Table row 11|Slovenia]]
that references the anchor (within the table), coded as |- id="Table row 11"
, makes the page scroll so selected row of the table is at the top of the browser view. Here, we use the template family {{Image label begin}}
, {{Image label small}}
, and {{Image label end}}
to lay out such a table for us:
Clicking on a country name scrolls
the list and shows the country's data on top
↦
Countries by percent of Avaaz members per popul.
The list can be scrolled manually or interactively

Row template
Regardless of whether wikitable format or HTML is used, the wikitext of the rows within a table, and sometimes even within a collection of tables, may have much in common, e.g.:
- the basic code for a table row
- code for color, alignment, and sorting mode
- fixed texts such as units
- special formats for sorting
In such a case, it can be useful to create a template that produces the syntax for a table row, with the data as parameters. This can have many advantages:
- easily changing the order of columns, or removing a column
- easily adding a new column if many elements of the new column are left blank (if the column is inserted and the existing fields are unnamed, use a named parameter for the new field to avoid adding blank parameter values to many template calls)
- computing fields from other fields, e.g. population density from population and area
- duplicating content and providing span tags with
display: none;
for the purpose of having one format for sorting and another for display
- easy specification of a format for a whole column, such as color and alignment
Example:
Using m:Help:Table/example row template (talk, backlinks, edit)
{| class="wikitable sortable"
|-
! scope="col" | a
! scope="col" | b
! scope="col" | a/b
{{Help:Table/example row template| 50|200}}
{{Help:Table/example row template| 8| 11}}
{{Help:Table/example row template|1000| 81}}
|}
gives:
a

Conditional table row
For a conditional row in a table, we can have:
{| class="wikitable"
{{ #if:1|{{!}}-
! scope="row" {{!}} row one, column one
{{!}}row one, column two}}
{{ #if: |{{!}}-
! scope="row" {{!}} row two, column one
{{!}}row two, column two}}
|-
! scope="row" {{!}} row three, column one
| row three, column two
|}
With comments to explain how it works:
{| class="wikitable"
<!--
Row one is shown because the '1' evaluates
to TRUE.
-->
{{ #if:1|{{!}}-
! scope="row" {{!}} row one, column one
<!--
Any {{!}}'s are evaluated to the pipe
character '|' since the template '!' just
contains '|'.
-->
{{!}}row one, column two}}
<!--
Row two is NOT shown because the space
between the ':' and the '|' evaluates to FALSE.
-->
{{ #if: |{{!}}-
! scope="row" {{!}} row two, column one
{{!}}row two, column two}}
<!--
Row three is shown.
-->
|-
! scope="row" {{!}} row three, column one
| row three, column two
|}
Which gives the following table: (note how the second row is missing)
row one, column one
row one, column two
row three, column one
row three, column two
Other table syntax
The types of table syntax that MediaWiki supports are:
- Wikicode
|
syntax
- HTML (and XHTML)
- Mixed XHTML and wikicode (Do not use)
All three are supported by MediaWiki and create (currently) valid HTML output, but the pipe syntax is the simplest. Mixed HTML and wikicode |
syntax (i.e., unclosed |
and |-
tags) don't necessarily remain browser-supported in the future, especially on mobile devices.
See also HTML element#Tables. Note, however, that the thead
, tbody
, tfoot
, colgroup
, and col
elements are currently not supported in MediaWiki, as of July 2015[update].

Pros
- Can preview or debug with any XHTML editor
- Can be indented for easier reading
- Well-known
- Insensitive to newlines
- No characters like "|", which can collide with template and parser function syntax
- Easy to write
- Easy to read
- Takes little space
- Can be learned quickly
Cons
- Tedious
- Takes a lot of space
- Difficult to read quickly
- Debugging more difficult because of tag pairing requirements
- Indented code might not match nesting.
- Confusing newline behaviour as they only occasionally break cells.
- Unfamiliar syntax for experienced HTML editors
- Rigid structure
- Cannot be indented for clarity
- HTML tag text may be easier to read than pipes, plus signs, dashes, etc.
- Requires using
{{!}}
to pass a |
character in a parameter.
- Sensitive to newlines; see Help:Newlines and spaces.
XHTML
Wiki-pipe
Pipe syntax in terms of the HTML produced
The pipe syntax, developed by Magnus Manske, substitutes pipes ( |
) and other symbols for HTML. There is an online script, which converts HTML tables to pipe-syntax tables.
The pipes must start at the beginning of a new line, except when separating parameters from content or when using ||
to separate cells on a single line. The parameters are optional.
Tables
A table is defined by {| parameters |}
, which generates <tag params>...</tag>
.
Rows
For each table, an HTML <tr>
tag is generated for the first row. To start a new row, use:
|-
which generates another <tr>
.
Parameters can be added like this:
|- params
which generates <tr params>
.
Note:
<tr>
tags are automatically opened before the first <td>
equivalent
<tr>
tags are automatically closed at another <tr>
equivalent and at the </table>
equivalent
Cells
Cells are generated either like this:
|cell1
|cell2
|cell3
or like this:
|cell1||cell2||cell3
which both generate:
<td>cell1</td>
<td>cell2</td>
<td>cell3</td>
.
The ||
equals a newline + |
.
Parameters in cells can be used like this:
|params|cell1||params|cell2||params|cell3
which results in:
<td params>cell1</td>
<td params>cell2</td>
<td params>cell3</td>
Headings
The code used produces a <th>...</th>
, functioning the same way as <td>...</td>
, but with different style and semantic meaning. A !
character is used instead of the opening |
, and !!
can be used like ||
, to enter multiple headings on the same line. Parameters still use "|", though. Example:
!params|cell1
Captions
A <caption>
tag is created by
|+ caption
which generates the HTML <caption>caption</caption>
.
You can also use parameters:
|+ params|caption
which generates <caption params>caption</caption>
.
Table cell templates
{{Table cell templates}} provide a set of templates to configure text and color in cells in a standard way, producing stock output such as "Yes", "No", and "n/a", on coloured backgrounds.
Square monitors
Using specific pixel widths as show herein is a deprecated practice. Avoid this sort of device-specific problem entirely by using flexible, relative sizing in %
values (for table proportions) and em
values (for images). Modern mobile devices with automatically shrink content to fit.
To format for a square device or window, use a tape measure. Determine the height of your rectangular screen. Using that figure, measure under the screen to determine the width the screen would be if it were square. Mark that location using pencil or tape under the screen. Drag the side of your browser’s window to that location so the window is square based on these measurements. Square monitors and reading windows are not able to contain tables and galleries made for wide rectangular screens. When a table or gallery is wider than the monitor, it makes every line of text wider than the screen as well. The px
amounts of the following gallery were determined after measuring the window to make sure it was square:
{| style="background: transparent; margin: auto;"
| [[File:Some window blinds.JPG|192x155px|thumb|left|Various window shades]]
| [[File:Vert-blinds-2145-rs.jpg|192x170px|thumb|left|Vertical blinds]]
| [[File:Gardine.jpg|192x155px|thumb|left|This is not a blind]]
|}
{| style="background: transparent; margin: auto;"
| [[File:Vorhang.jpg|192x155px|thumb|left|Solid shade]]
| [[File:Jalousie-1.jpg|328x55px|thumb|left|Horizonal blinds]]
|}
{| style="background: transparent; margin: auto;"
| [[File:Some window blinds.JPG|205px|thumb|left|Shade, shutters; vertical and horizontal blinds.]]
| [[File:Miniblinds detail of mechanism.jpg|388px|thumb|left|<!--
-->Detail of turning rod (blind stick) attachment on miniblinds]]
|}
Displays as:
Vertically oriented column headers
Sometimes it is desirable (such as in a table predominantly made of numbers) to rotate text such that it proceeds from top to bottom or bottom to top instead of from left to right or right to left. Currently, browser support for this type of styling as a component of HTML or CSS is sporadic (Internet Explorer is one of the few browsers that supports this in cascading stylesheets, albeit in a non-standard way). An alternative solution that works in most if not all browsers is to use images in place of the text. For instance, the following table uses SVG images instead of text to produce the rotated column headings:
05/08
4266
7828
7282
1105
224
161
916
506
231
04/08
4127
6190
6487
1139
241
205
1165
478
301
Normally, one problem with this approach is that readers are directed to different pages when they click on the images. To eliminate this problem—or to direct readers to a different page—you can use the |link=
parameter of the File:
specification. A column heading can be coded as follows:
! style="width:3em;" | [[File:wpvg vg project.svg |alt=VG: Project |link='''Wikipedia:WikiProject Video games''']]
The image wikilinks to the page Wikipedia:WikiProject Video games.
By setting the link to an empty string (e.g. [[File:wpvg hd date page.svg |link=]]
), no navigation occurs when visitors click on an image. Note that it might also be a good idea to color the image text blue if you are using the images as links. Also, SVG is the preferred image format in this case because it can be re-scaled to any size while producing fewer artifacts.
A more serious potential problem is that the "rotated text" is not text that can be used by screen readers and other technologies for visually disabled users. So those users wouldn't be able to "read" the column headings. Also, automated search engine Web crawlers would not be able to read it either. This is solved by always using the |alt=
parameter in the File:
specification of each image to provide the same text as in the rotated image; see |alt=VG: Project
in the example above.
Wikitable as image gallery
This section is still recommending deprecated fixed-pixel sizes for images, and should be updated with relative sizes in em
units.
A wikitable can be used to display side-by-side images, in the manner similar to that of an image gallery (formatted by <gallery>...</gallery>
), but with larger images and less vacant area around photos.
A simple, framed gallery can be formatted using class="wikitable"
to generate the minimal thin lines around images within the table:
{| class="wikitable"
|-
|<!--col1-->[[File:Worms 01.jpg|130px]]
|<!--col2-->[[File:Worms Wappen 2005-05-27.jpg|125px]]
|<!--col3-->[[File:Liberty-statue-with-manhattan.jpg|125px]]
|<!--col4-->[[File:New-York-Jan2005.jpg|125px]]
|-
|<!--col1-->Nibelungen Bridge to Worms
|<!--col2-->Worms and its sister cities
|<!--col3-->Statue of Liberty
|<!--col4-->New York City
|}<!--end wikitable-->
Nibelungen Bridge to Worms
Worms and its sister cities
Statue of Liberty
New York City
An advantage of wikitable image galleries, compared to <gallery>
formatting, is the ability to "square" each image when similar heights are needed, so consider putting two-number image sizes (such as 199x95px
), where the second number limits height:
{| class="wikitable"
|<!--col1-->[[File:Worms 01.jpg|199x95px]]
|<!--col2-->[[File:Worms Wappen 2005-05-27.jpg|199x95px]]
|<!--col3-->[[File:Liberty-statue-with-manhattan.jpg|199x95px]]
|<!--col4-->[[File:New-York-Jan2005.jpg|100x95px]]<!--smaller-->
|-
|<!--col1-->Nibelungen Bridge to Worms
|<!--col2-->Worms and its sister cities
|<!--col3-->Statue of Liberty
|<!--col4-->New York City
|}
Note the three images sized 199x95px
appear identical height, of 95px
(the fourth image purposely smaller). The "95px" forces height, while 199x
fits the various widths (it could even be 999x
):
Nibelungen Bridge to Worms
Worms and its sister cities
Statue of Liberty
New York City
Therefore, the use of size 199x95px
(or 999x95px
, or whatever) produces the auto-height-sizing beyond the <gallery>
tag, and with the option to set taller thumbnails (199x105px
), or even to have some images purposely smaller than other images of 95px
height. A very short height (e.g. 70px
) allows many more images across the table:
{| class="wikitable"
|-
|<!--col1-->[[File:Worms 01.jpg|199x70px]]
|<!--col2-->[[File:Gold star on blue.gif|199x70px]]
|<!--col2-->[[File:Worms Wappen 2005-05-27.jpg|199x70px]]
|<!--col4-->[[File:Gold star on deep red.gif|199x70px]]
|<!--col3-->[[File:Liberty-statue-with-manhattan.jpg|199x70px]]
|<!--col6-->[[File:Gold star on blue.gif|199x70px]]
|<!--col4-->[[File:New-York-Jan2005.jpg|199x70px]]<!--same height-->
|-
|}
The above wikitable-coding produces the result below, of 7 columns:
Once images have been placed in a wikitable, control of formatting can be adjusted when more images are added.
Shifting/centering
Images within a wikitable can be shifted by inserting non-breaking spaces (
) before or after the image code (e.g., [[Image:...]]
). However, auto-centering simply requires use of the |center
parameter (see WP:Extended image syntax#Location).
In the example below, note how Col2 uses |center
, but Col3 uses
:
{| class="wikitable"
|-
|<!--Col1-->[[File:Domtoren vanaf Brigittenstraat.jpg|299x125px]]
|<!--Col2-->[[File:Utrecht 003.jpg|299x125px|center]]
|<!--Col3--> [[File:Uitzicht--Domtoren.jpg|299x125px]]
|-
|<!--Col1-->Dom tower from Brigittenstraat
|<!--Col2-->Cloister garth of the Utrecht Dom Church
|<!--Col3--> <small>View from bell tower</small>
|}
The above coding generates the table below: note the middle garden image is centered (but not the left image), and the right image has 2 spaces before "View...", to give an approximation of centering:
Dom tower from Brigittenstraat
Cloister garth of the Utrecht Dom Church
View from bell tower
Also note that the tag <small>...</small>
made a smaller-text-size caption. Fonts also can be sized by percent (style="font-size: 87%;"
), where the exact percent-size as displayed depends on the various sizes allowed for a particular font; the browser will approximate to the nearest possible size.
| style="font-size: 87%;" | View from bell tower
The column attribute, above, uses style=
to set the font size for the caption, following the second pipe symbol.
A font-size: 65%;
is excessively small, while font-size: 87%;
is a mid-size font, slightly larger than that produced by the tag <small>
.
Generate a chart with a table
As of July 2015[update], these templates are still broken due the MediaWiki Toolserver no longer existing, and the code not having migrated to MediaWiki Labs. There is no information on when or if it will be fixed. Use these templates to interface with the the meta:Visualizer for Wikimedia projects formerly located at http://toolserver.org/~al/.
This is done using {{visualizer}} or any another template that uses the {{metavisualizer}} meta-template.
Converting spreadsheets and database tables to wikitable format
To convert from spreadsheets (such as those produced by Gnumeric, Microsoft Excel, or LibreOffice/OpenOffice.org/StarOffice Calc), you can use the Copy & Paste Excel-to-Wiki converter, or the MediaWiki Tables Generator.
The online csv2wp script (documentation) converts comma-separated values (CSV) format to wikitable pipe syntax. You may use this to import tables from both spreadsheets and databases (such as MySQL, PostgreSQL, SQLite, FileMaker Pro, Microsoft SQL Server & Access, Oracle, DB2, etc.).
Tables and the Visual Editor
It is now possible to copy and paste a table from a web page directly into the Visual Editor (VE). To do so safely, use a sandbox and check the table for proper coding in wikitext source mode and proper display in the Visual Editor and in preview mode. One of the most useful features is the ability to add and delete columns and rows within the VE; while edting, left-click on the left of a row, or the top of a column to see the options.
