<h1>Visibility collapse</h1>
|
|
<a href="https://drafts.csswg.org/css-tables-3/#computing-the-table-height">Spec</a>
|
|
<p>
|
|
Collapsing a row group but making its rows visible should still result in a
|
|
collapsed row group.
|
|
</p>
|
|
<x-table id="one">
|
|
<x-tbody>
|
|
<x-tr>
|
|
<x-td>
|
|
<span>row 1</span>
|
|
</x-td>
|
|
<x-td>
|
|
<span></span>
|
|
</x-td>
|
|
</x-tr>
|
|
<x-tr>
|
|
<x-td>
|
|
<span>row 2</span>
|
|
</x-td>
|
|
<x-td>
|
|
<span></span>
|
|
</x-td>
|
|
</x-tr>
|
|
</x-tbody>
|
|
<x-tr id="thirdRowRef">
|
|
<x-td>
|
|
<span>row 3</span>
|
|
</x-td>
|
|
<x-td>
|
|
<span></span>
|
|
</x-td>
|
|
</x-tr>
|
|
</x-table>
|
|
When row group is collapsed, visible rows within the row group are still collapsed and therefore invisible.
