Below is a documentation on how to edit tables in wikitext. To learn how to edit tables in Visual Editor, see Help:Tables
Wiki table markup summary
{|
table start
|+
table caption,optional; only between table start and first table row
|-
table row,optional on first row -- wiki engine assumes the first row
!
table header cell, optional. Consecutive table header cells may be added on same line separated by double marks (!!) or start on new lines, each with its own single mark (!).
|
table data cell, required! Consecutive table data cells may be added on same line separated by double marks (||) or start on new lines, each with its own single mark (|).
|}
table end
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.
XHTML attributes. Each mark, except table end, optionally accepts one or more XHTML 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 XHTML 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.
Escaping to insert a pipe (|) character into a table use the <nowiki> markup
Toolbar in Wikitext mode

The formatting toolbar offers one of the easiest ways to add a new table to a page. To add a table, select the "advanced" drop down menu and then click on the gray table box. This will prompt an input box for creating a table. When the insert button is clicked, the code for the new table is inserted into the wiki page. Simply replace the example text with your own text to finish creating the table.
Basics
The following table lacks borders and good spacing but shows the simplest wiki markup table structure.
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 |.
The default table formatting uses the "border-collapse: separate" model, which adds table cell spacing (which also separates the the table outer border from its content cells). Even with a zero cellspacing, the borders of consecutive cells (and of the overall table container) will add up, so to get a one-pixel separation between cells, you need to selectively remove one or more of the four borders of cells.
Such tables may be formatted more simply, using the "border-collapse: collapse" CSS property; in this table formatting model, the cellspacing attribute (or the CSS "border-spacing:" property) and the table's "padding:" CSS property is ignored and only the larger border of adjascent inner cells (or the table border for outer cells) will be used.
An example of the above for one-pixel table border, using each model (without need for external extensions):
When using the "border-width:" CSS shortcut property, the order of the four space-separated specified values is: top, right, bottom, left. When there are fewer than 4 values, the value for left takes its default from the value for right, the value for bottom takes its default from the value for top, and the value for right takes its default from the value for top.
The HTML attributes (such as "width=", "border=", "cellspacing=", "cellpadding=") do not need any length unit (the pixel unit is assumed). The CSS style properties (which override the HTML attributes) require an explicit length unit (if the value is not 0) such as "px" for the pixel.
HTML colspan and rowspan
You can use HTML colspan and rowspan attributes on cells for advanced layout.
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 medias, 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:
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 (| -6) or use in-line cell markup (|| -6).
CSS vs Attributes
Table borders specified through CSS rather than the border attribute will render incorrectly in a small subset of text browsers.
