<p>This should be a 100px by 100px blue square:</p>
<p>The table grid is 2x2, 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 are not merged together because they are all defined explicitely by a table-column or a table-row</p>
