 * Tables redirects here; for information about database table structure, see.

Tables may be created in wiki pages. As a general rule, it is best to avoid using a table unless you need one. Table markup often complicates page editing.

Wiki table markup summary

 * The above marks must start on a new line except the double  and   for optionally adding consecutive cells to a line. However, blank spaces at the beginning of a line are ignored.
 * HTML attributes. Each mark, except table end, optionally accepts one or more HTML attributes. Attributes must be on the same line as the mark. Separate attributes from each other with a single space.
 * Cells and caption ( or ,   or  , and  ) hold content. So separate any attributes from content with a single pipe . Cell content may follow on same line or on following lines.
 * Table and row marks ( and  ) do not directly hold content. Do not add pipe  after their optional attributes. If you erroneously add a pipe after attributes for the table mark or row mark the parser will delete it and your final attribute if it was touching the erroneous pipe!
 * Content may (a) follow its cell mark on the same line after any optional HTML attributes or (b) on lines below the cell mark. Content that uses wiki markup that itself needs to start on a new line, such as lists, headings, or nested tables, must be on its own new line.
 * Pipe character as content. To insert a pipe character into a table, use the &lt;nowiki&gt; &lt;/nowiki&gt; escaping markup.

Basics
The following table lacks borders and good spacing but shows the simplest wiki markup table structure.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

The cells in the same row can be listed on one line separated by  (two pipe symbols). If the text in the cell should contain a line break, use  instead.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Extra spaces within cells in the wiki markup, as in the wiki markup below, do not affect the actual table rendering.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

You can have longer text or more complex wiki syntax inside table cells, too:

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Table headers
Table headers can be created by using " " (exclamation mark) instead of " " (pipe symbol). Headers usually show up bold and centered by default.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Caption
A table caption can be added to the top of any table as follows.

class="wikitable"
Basic styling (light gray background, borders, padding and align left) can be achieved by adding class="wikitable".

HTML colspan and rowspan
You can use HTML colspan and rowspan attributes on cells for advanced layout.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

HTML attributes
You can add HTML attributes to tables. For the authoritative source on HTML attributes, see the W3C's HTML Specification page on tables.

Attributes on tables
Placing attributes after the table start tag applies attributes to the entire table.

{| style="width:100%" ! style="width: 50%;"| You type ! style="width: 50%;"| You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Attributes on cells
You can put attributes on individual cells. For example, numbers may look better aligned right.

You can also use cell attributes when you are listing multiple cells on a single line. Note that the cells are separated by, and within each cell the attribute(s) and value are separated by.

{| style="width:100%" ! style="width: 50%;"| You type ! style="width: 50%;"| You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Attributes on rows
You can put attributes on individual rows, too.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Simple one-pixel table border
An example of a one-pixel table border:

{| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }

Border width
If "border-width:" has only one number, it is for all four border sides: {| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }

If "border-width:" has more than one number, the four numbers are for top, right, bottom, left (REMEMBER clockwise order &uarr;&rarr;&darr;&larr;):

{| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }


 * When there are fewer than 4 values :
 * three values i.e.,  ,  : then the default value for   is the one of   (second value). Width is then the same on left and right side.
 * two values i.e.,  : then the default value for   is the one of   (first value), and   by default is assigned the value of   (second value). Width on top is then the same as on bottom; width on left is the same as on right.
 * one value i.e. : then the default value for   is the one of   and it is the same for   and  . The fourth width are the same and build a regular border. This is a writing shortcut.

Another method to define the widths of the four sides of a cell is to use "border-left", "border-right", "border-top" and "border-bottom": {| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }

With HTML attributes and CSS styles
style attributes can be added with or without other HTML attributes.

Padding
{| style="width:100%;" ! style="width: 50%;"| You type ! style="width: 50%;"| You get
 * -valign=top
 * style="padding:10px" |


 * }

Attributes
Attributes can be added to the caption and headers as follows.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Column width
Column width can be added as follows.

Accessibility of table header cells
Table header cells do not explicitly specify which table data cells they apply to (those on their right on the same row, or those below them on the same column). When the table is rendered in a visual 2D environment, this is usually easy to infer.

However when tables are rendered on non-visual media, you can help the browser to determine which table header cell applies to the description of any selected cell (in order to repeat its content in some accessibility helper) using a scope="row" or scope="col" attribute on table header cells. In most cases with simple tables, you'll use scope="col" on all header cells of the first row, and scope="row" on the first cell of the following rows:

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Table alignment
Table alignment is achieved by using CSS. The table alignment is controlled by margins. A fixed margin on one side will make the table to be aligned to that side, if on the opposite side the margin is defined as auto. To have a table center aligned, you should set both margins to auto

For example, a right-aligned table:

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

And a center-aligned table:

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Table floating around text
If you align a table to the right or the left side of the page, the text that comes after the table starts at the end of it, leaving an empty space around the table. You can make the text to be wrapped around the table by making the table to float around the text instead of just aligning it. This can be achieved using the  CSS attribute, which can specify where the table floats to the right side or to the left. When using float, margins doesn't control table alignment and can be used to specify the margin between the table and the surrounding text.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|

Cell contents alignment
The alignment of cell contents can be controlled with 2 different CSS properties:  and. can be specified at the table, row or individual cells, while  only can be specified at individual rows or cells.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Negative numbers
If you start a cell on a new line with a negative number with a minus sign (or a parameter that evaluates to a negative number), your table can get broken, because the characters  will be parsed as the wiki markup for table row, not table cell. To avoid this, insert a space before the value or use in-line cell markup.

CSS vs attributes
Table borders specified through CSS rather than the border attribute will render incorrectly in a small subset of text browsers.

Common attributes for columns, column groups and row groups
The MediaWiki syntax for tables currently offers no support for specifying common attributes for columns (with the HTML element ), column groups (HTML element  ) and row groups (HTML elements ,   and  ). Those standard HTML elements are not accepted even in their HTML or XHTML syntax.

All the rows and cells (header or data) of the table are rendered within a single implicit row group (HTML element ) without any attributes or styles.

Tables and the Visual Editor (VE)

 * See also: 

See T108245: "Fully support basic table editing in the visual editor". See the list of tasks. Finished tasks are struck. It can be difficult to figure out from the technical language there what exactly has been improved, or what features have been added. Please add explanatory info below.

Can now move or delete columns and rows
Click on a column or row header. Then click on the arrow. From the popup menu click on "Move" or "Delete".

Insert blank row or column
From the same popup menu click on "Insert".

Copy table from web page to Visual Editor
It is 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.
