<mtable>

Baseline Widely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2023.

* Some parts of this feature may have varying levels of support.

The<mtable>MathML element allows you to create tables or matrices. Its children are<mtr> elements (representing rows), each of them having<mtd> elements as its children (representing cells). These elements are similar to<table>,<tr> and<td> elements ofHTML.

Attributes

This element's attributes include theglobal MathML attributes. Some browsers may also support the following attributes:

alignNon-standard

Specifies thevertical 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 thealign attribute can end with arow number (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.

columnalignNon-standard

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) andright.

columnlinesNon-standard

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 anddashed.

columnspacingNon-standard

Specifies the space between table columns. Multiple values separated by space are allowed and apply to the corresponding columns (e.g.,columnspacing="1em 2em"). Possible values are<length-percentage>.

frameNon-standard

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

framespacingNon-standard

Specifies additional space added between the table and frame. The first value specifies the spacing on the right and left; the second value specifies the spacing above and below. Possible values are<length-percentage>.

rowalignNon-standard

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 andtop.

rowlinesNon-standard

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 anddashed.

rowspacingNon-standard

Specifies the space between table rows. Multiple values separated by space are allowed and apply to the corresponding rows (e.g.,rowspacing="1em 2em"). Possible values are<length-percentage>.

widthNon-standard

A<length-percentage> indicating the width of the entire table.

Note:For thewidth attribute, some browsers may also acceptlegacy MathML lengths.
