Log Message:
-----------
auto table layout doesn't honor "max-width" on table cells, when distributing
width between them

Reviewed by Alan Baradlay.
In AutoTableLayout::recalcColumn(), when a cell has an explicit CSS width,
the value is stored into columnLayout.logicalWidth without consulting the
cell's max-width. This causes max-width to be ignored during fixed-width
column distribution in layout().
Clamp the resolved logicalWidth by the cell's CSS max-width right after
it is computed, so the clamped value flows into columnLayout.logicalWidth
and is respected during width distribution.
