I have a very specific html table construct that seems to reveal a Gecko bug.
Here's a distilled version of the problem. Observe the following table in a gecko-based browser (FF, for example): (you'll have to copy and paste this into a new file)
<style>
table.example{
border-collapse:collapse;
}
table.example td {
border:1px solid red;
}
</style>
<table class="example">
<thead>
<tr>
<th>1</th>
<th>2</th>
<th>3</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>2</td>
<td rowspan="3">3</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>1</td>
<td rowspan="2">2</td>
</tr>
<tr>
<td>1</td>
<td>3</td>
</tr>
</tbody>
</table>
There's a line missing over the "3" in the bottom-right cell -- view it in any other browser and the line will appear as expected. Interestingly, ditch the thead section of the table and look what we get:
<style>
table.example{
border-collapse:collapse;
}
table.example td {
border:1px solid red;
}
</style>
<table class="example">
<tbody>
<tr>
<td>1</td>
<td>2</td>
<td rowspan="3">3</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>1</td>
<td rowspan="2">2</td>
</tr>
<tr>
<td>1</td>
<td>3</td>
</tr>
</tbody>
</table>
Doing that makes it work. Has anyone seen this? I suppose I'll just get rid of my thead section for now as a workaround though it makes the table rather less accessible.
