Seen in output for a simple test case for javadoc ...

This is for no modules, and a package containing three classes. The HTML is for the list of classes on the package summary page:


<main role="main">
<div class="header">
<h1 title="Package" class="title">Package&nbsp;pb2</h1>
</div>
<div class="contentContainer">
<ul class="blockList">
<li class="blockList">
<table class="typeSummary">
<caption><span>Class Summary</span><span class="tabEnd">&nbsp;</span></caption>
<tr>
<th class="colFirst" scope="col">Class</th>
<th class="colLast" scope="col">Description</th>
</tr>
<tbody>
<tr class="altColor">
<th class="colFirst" scope="row"><a href="Alpha.html" title="class in pb2">Alpha</a></th>
<td class="colLast">
<div class="block">Class mb/pb2/Alpha.</div>
</td>
</tr>
<tr class="rowColor">
<th class="colFirst" scope="row"><a href="Beta.html" title="class in pb2">Beta</a></th>
<td class="colLast">
<div class="block">Modified Class mb/pb2/Beta.</div>
</td>
</tr>
<tr class="altColor">
<th class="colFirst" scope="row"><a href="Gamma.html" title="class in pb2">Gamma</a></th>
<td class="colLast">
<div class="block">Class mb/pb2/Gamma.</div>
</td>
</tr>
</tbody>
</table>
</li>
</ul>
</div>
</main>


Note that between the <caption> element and the <tbody> element is a header row that is not enclosed in <thead>, but which should be.
