<mlabeledtr>

The MathML <mlabeledtr> element is used to represent a label in a row either on the left or on the right side (determined using the side attribute on the <mtable> element). Child elements of <mlabeledtr> must be <mtd> elements. The first child is the label whereas all other children are representing row contents and are treated identically to children of <mtr> elements.

Gecko-specific notes

Starting with Gecko 9.0 (Firefox 9.0 / Thunderbird 9.0 / SeaMonkey 2.6) labels are hidden by default (mlabeledtr > mtd:first-child {display: none}) and will longer break the table rendering completely (see bug 356870). For the actual implementation of this element see bug 689641.
