Seen in the output from a small test program:

<div id="memberSummary_tabpanel" role="tabpanel">
<table aria-labelledby="t0">
<tr>
<th class="colFirst" scope="col">Modifier and Type</th>
<th class="colSecond" scope="col">Method</th>
<th class="colLast" scope="col">Description</th>
</tr>
<tbody>
<tr class="altColor" id="i0">
<td class="colFirst"><code>java.lang.String</code></td>
<th class="colSecond" scope="row"><code><span class="memberNameLink"><a href="#m2()">m2</a></span>()</code></th>
<td class="colLast">
<div class="block">This is Base::m2.</div>
</td>
</tr>
</tbody>
</table>
</div>

Note that the first row is not enclosed in a <thead>. It should be.
