{{MathMLRef}}

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

Attributes

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

• align {{Non-standard_Inline}}

  • : 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.

• columnalign {{Non-standard_Inline}}

  • : 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 {{Non-standard_Inline}}

  • : 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 {{Non-standard_Inline}}

  • : 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>.

• frame {{Non-standard_Inline}}

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

• framespacing {{Non-standard_Inline}}

  • : 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>.

• rowalign {{Non-standard_Inline}}

  • : 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 {{Non-standard_Inline}}

  • : 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.

• rowspacing {{Non-standard_Inline}}

  • : 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>.

• width {{Non-standard_Inline}}

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

Note: For the width attribute, some browsers may also accept legacy MathML lengths.

      <mtd><mi>B</mi></mtd>
    </mtr>
    <mtr>
