<h1>HTML5 Table Formatting algorithm (row/column grid computation)</h1>

<p>This should be a 100px by 100px blue square:</p>
|
|
<p>The table grid is 1x1, so the table is not empty and follows step 3A of the table layout algorithm (which adds anonymous cell boxes)</p>
|
|
<p>The consecutive tracks were merged together because they are not all defined explicitely by a table-column or a table-row, and share the same set of cells</p>
|
|
<p>Two 25px border-spacing causes the addition of 50px (track is 50x50)</p>
