How to use the MathML Labeled Row Element: "mlabeledtr"?

"mlabeledtr" is the MathML Table Row Element that allows you to specify a labeled row in a "mtable" element.

The syntax for "mlabeledtr" element is:

<mlabeledtr>label cell cell ... </mlabeledtr>

Here is an example of using the "mlabeledtr" element.

<math><mtable frame="solid" side="right">          
  <mlabeledtr><mtd><mtext>1</mtext></mtd>
  <mtd><mi>x</mi><mo>=</mo><mi>a</mi></mtd></mlabeledtr>     
  <mlabeledtr><mtd><mtext>2</mtext></mtd>
  <mtd><mi>y</mi><mo>=</mo><mi>b</mi></mtd></mlabeledtr>
  </mtable></math>
    $\begin{array}{||}\hline \text{1}& x=a\text{2}& y=b\\ \hline\end{array}$

Note that some Web browsers may not support "mlabeledtr" elements correctly. In that case, you may want to add row labels as extra cells in regular "mtr" elements as shown below:

<math><mtable frame="solid" columnalign="left" columnspacing="0.5in">          
  <mtr><mtd><mi>x</mi><mo>=</mo><mi>a</mi></mtd>
  <mtd><mtext>Vertical line</mtext></mtd></mtr>     
  <mtr><mtd><mi>y</mi><mo>=</mo><mi>b</mi></mtd><mtd>
  <mtext>Horizontal line</mtext></mtd></mtr>
  </mtable></math>
    $\begin{array}{|ll|}\hline x=a& \text{Vertical line}\\ y=b& \text{Horizontal line}\\ \hline\end{array}$
