| <h1>Visibility collapse</h1> |
| <a href="https://drafts.csswg.org/css-tables-3/#visibility-collapse-cell-rendering">Spec</a> |
| <p> |
| Setting a row to visibility:collapse changes table height but not width. |
| Here, the spanning cell is the only cell in its row. |
| </p> |
| <table id="one"> |
| <tr id="spanningRowRef"> |
| <td rowspan="5">B<br>B<br>B<br>B<br>B</td> |
| </tr> |
| <tr id="firstRowRef"> |
| <td>aaaa</td> |
| </tr> |
| <tr> |
| <td>bbbb</td> |
| </tr> |
| <tr id="thirdRowRef"> |
| <td>cccc</td> |
| </tr> |
| <tr id="fourthRowRef"> |
| <td>dddd</td> |
| </tr> |
| </table> |
| Bottom table is identical to top except second row has been collapsed. |
| The spanning cell's height shrinks and is clipped. |
| <table id="two"> |
| <tr id="spanningRow"> |
| <td rowspan="5" id="spanningCell">B<br>B<br>B<br>B<br>B</td> |
| </tr> |
| <tr id="firstRow"> |
| <td>aaaa</td> |
| </tr> |
| <tr id="secondRow" style="visibility: collapse"> |
| <td>bbbb</td> |
| </tr> |
| <tr id="thirdRow"> |
| <td>cccc</td> |
| </tr> |
| <tr id="fourthRow"> |
| <td>dddd</td> |
| </tr> |

| This text should not intersect with the table. |
