| <h1>Fixed tables with padding: Compute column computed widths from assignable table width</h1> |
| |
| <p>This test is the similar to table-width-redistribution-fixed.html, |
| except that all cells have 6px padding. The comments in this test refer to padding incompatibilities only.</p> |
| |
| <p class="error">Percentage sizes and box-sizing are handled differently in FF/Chrome. In Chrome, %ge size is always treated as border-box size: column width = % * table width. In FF, box-sizing:content-box, %ge size is % * table width + border_padding, box-sizing:border-box same as Chrome. </p> |
