<p>A row of cells in a tabular container.</p>
<p>Rows contain <rref>cell</rref> or <rref>gridcell</rref> <a>elements</a>, and thus serve to organize the <rref>table</rref> or <rref>grid</rref>.</p>
<p>In a <rref>treegrid</rref>, authors MAY mark rows as expandable, using the <sref>aria-expanded</sref> <a>attribute</a> to indicate the present status. This is not the case for an ordinary <rref>table</rref> or <rref>grid</rref>, in which the <sref>aria-expanded</sref> attribute is not present.</p>
<p>Rows contain <rref>cell</rref> or <rref>gridcell</rref> <a>elements</a>, and thus serve to organize a <rref>table</rref>, <rref>grid</rref>, or <rref>treegrid</rref>.</p>
<p>
While the row role can be used in <rref>tables</rref>, <rref>grids</rref>, and <rref>treegrids</rref>, the semantics of <sref>aria-expanded</sref>, <pref>aria-posinset</pref>, <pref>aria-setsize</pref>, and <pref>aria-level</pref> are only applicable to the hierarchical structure of an interactive tree grid.
Therefore, authors MUST NOT apply <sref>aria-expanded</sref>, <pref>aria-posinset</pref>, <pref>aria-setsize</pref>, and <pref>aria-level</pref> to a <rref>row</rref> that descends from a <rref>table</rref> or <rref>grid</rref>, and user agents SHOULD NOT expose any of these four properties to assistive technologies unless the <rref>row</rref> descends from a <rref>treegrid</rref>.
</p>
<p>Authors MUST ensure <a>elements</a> with <a>role</a> <code>row</code> are contained in, or <a>owned</a> by, an element with the role <rref>table</rref>, <rref>grid</rref>, <rref>rowgroup</rref>, or <rref>treegrid</rref>.</p>
