buster%netscape.com 21e08756c0 irrationally-specified table (one where the width attributes of various rows don't add up to the same value,
and/or to the width attribute on the table itself), the rule is to try to give the column the largest value
assigned to it by any cell intersecting that column.
Separate storage is maintained for a column's natural desired width (width from any source other than a cell
with a colspan) and the maximum contribution to the column's width from any cell with a colspan.
