Don't shrink table columns when handling cells with greater spanning (#32458)

For example:
```html
<table border="1">
  <tr>  <td></td>  <td></td>  </tr>
  <tr>  <td colspan="2"></td>  </tr>
</table>
```
We should initially size the columns according to the cells in the first
row since they have a span of 1. Then we handle the cell in the second
row with a span of 2, this should be able to increase the size of the
columns, but never decrease them.
