<mtable>

The MathML <mtable> element allows you to create tables or matrices. Inside a <mtable> only <mtr> and <mtd> elements may appear. These elements are similar to <table> , <tr> and <td> elements of HTML.

Attributes

align

Specifies the vertical alignment of the table with respect to its environment.
Possible values are:

• axis (default): The vertical center of the table aligns on the environment's axis (typically the minus sign).
• baseline: The vertical center of the table aligns on the environment's baseline.
• bottom: The bottom of the table aligns on the environments baseline.
• center: See baseline.
• top: The top of the table aligns on the environments baseline.

In addition, values of the align attribute can end with a rownumber (e.g. align="center 3"). This allows you to align the specified row of the table rather than the whole table. A negative Integer value counts rows from the bottom of the table. Starting with Gecko 8.0 (Firefox 8.0 / Thunderbird 8.0 / SeaMonkey 2.5) the interpretation of negative values has been corrected (bug 601436). In Gecko 17.0 (Firefox 17.0 / Thunderbird 17.0 / SeaMonkey 2.14) the parsing has been updated to treat whitespace correctly.

Unimplemented

class, id, style

Provided for use with stylesheets.

columnalign

Specifies the horizontal alignment of the cells. Multiple values separated by space are allowed and apply to the corresponding columns (e.g. columnalign="left right center"). Possible values are: left, center (default) and right.

columnlines

Specifies column borders. Multiple values separated by space are allowed and apply to the corresponding columns (e.g. columnlines="none none solid"). Possible values are: none (default), solid and dashed.

columnspacing

Specifies the space between table columns.

Unimplemented columnwidth

Specifies the width of table columns.

displaystyle

A Boolean value specifying whether more vertical space is used for displayed equations or, if set to false, a more compact layout is used to display formulas. The main effect is that larger versions of operators are displayed, when displaystyle is set to true.

Unimplemented equalcolumns

A Boolean value indicating whether to force all columns to have the same total height. false is default.

Unimplemented equalrows

A Boolean value indicating whether to force all rows to have the same total height. false is default.

frame

Specifies borders of the entire table. Possible values are: none (default), solid and dashed.

framespacing

Specifies additional space added between the table and frame.

groupalign

Unimplemented

href

Used to set a hyperlink to a specified URI.

mathbackground

The background color. You can use #rgb, #rrggbb and HTML color names.

mathcolor

The text color. You can use #rgb, #rrggbb and HTML color names.

Unimplemented minlabelspacing

A length value specifing the minimum space between a label and the adjacent cell in the row.

rowalign

Specifies the vertical alignment of the cells. Multiple values separated by space are allowed and apply to the corresponding rows (e.g. rowalign="top bottom axis"). Possible values are: axis, baseline (default), bottom, center and top.

rowlines

Specifies row borders. Multiple values separated by space are allowed and apply to the corresponding rows (e.g. rowlines="none none solid"). Possible values are: none (default), solid and dashed.

Unimplemented rowspacing

Specifies the space between table rows.

Unimplemented side

Specifies the position where <mlabeledtr> label elements should be placed. Possible values are: left, right (default), leftoverlap and rightoverlap.

width

Specifies the width of the entire table. Accepts length values.
