HTML5 Table Formatting algorithm and Fixed Layout (row/column grid computation)

Verifies how browsers deal with implicit tracks from which no cell does originate in fixed mode

This should be a 100px by 50px blue rectangle:

The table grid is 1x3, so the table is not empty and follows step 3A of the table layout algorithm

The consecutive columns were merged not together because the table-layout is fixed, but consecutive rows were.

Each track has a 0px breadth; the table width (respect. height) comes from 4x (respect. 2x) 25px-wide border spacings
