Problems with COLSPAN and WIDTH

Each block of tables should be identical.

Sized Tables

The following tables have width=400, which should make them the same width as the red lines which are caused by DIVs:

260/140

plain width=140
colspan=2 width=400
width=260 plain
colspan=2 width=400
width=260 width=140
colspan=2 width=400
width=260 width=140
colspan=2
width=65% plain
colspan=2
plain width=35%
colspan=2
width=65% width=35%
colspan=2

140/260

width=140 plain
colspan=2 width=400
plain width=260
colspan=2 width=400
width=140 width=260
colspan=2 width=400
width=140 width=260
colspan=2
width=35% plain
colspan=2
plain width=65%
colspan=2
width=35% width=65%
colspan=2

50%

width=50% plain
colspan=2 width=400
plain width=50%
colspan=2 width=400
width=50% width=50%
colspan=2 width=400
plain plain
colspan=2 width=400
width=200 width=200
colspan=2

Tables Without Width

The following tables have no width. They should still be the same size, by virtue of them having a 400 pixel cell and no padding/margin/borders.

260/140

plain width=140
colspan=2 width=400
width=260 plain
colspan=2 width=400
width=260 width=140
colspan=2 width=400
width=260 width=140
colspan=2

140/260

width=140 plain
colspan=2 width=400
plain width=260
colspan=2 width=400
width=140 width=260
colspan=2 width=400
width=140 width=260
colspan=2

50%

width=50% plain
colspan=2 width=400
plain width=50%
colspan=2 width=400
width=50% width=50%
colspan=2 width=400
plain plain
colspan=2 width=400
