| <h1>HTML5 Table Formatting algorithm and Fixed Layout (row/column grid computation)</h1> |
| <p>Verifies how browsers deal with implicit tracks from which no cell does originate in fixed mode</p> |
| |
| <hr/> |
| <p>This should be a 100px by 50px blue rectangle:</p> |
| <p>The table grid is 1x3, so the table is not empty and follows step 3A of the table layout algorithm</p> |
| <p>The consecutive columns were merged not together because the table-layout is fixed, but consecutive rows were.</p> |
| <p>Each track has a 0px breadth; the table width (respect. height) comes from 4x (respect. 2x) 25px-wide border spacings</p> |
| <x-table style="table-layout: fixed; width: 0; background: blue; border-spacing: 25px"> |
| <x-tr><x-td width="0" height="0" colspan="3" rowspan="3" style="padding: 0"></x-td></x-tr> |
| </x-table> |
