The issue here is that the width attribute specified for the table is greater
than the sum of widths specified for the columns (in the original page, 733 > 24
+ 682 + 24  = 730; in my testcase 125 > 24 + 100 = 124).
The question is which column(s) the extra pixel(s) are assigned to. IE seems to
(correctly, IMO) favor the larger column, so the first (24px) column remains in
its specified width.
Mozilla/FF, on the other hands, adds the first extra pixel to the width of the
first column, causing the 24px background gif to wrap into the 25th pixel.

iirc we assign the extra width to all columns, proportinally (that is, each
column gets a fraction of the extra width proportional to the fraction of total
table width in that column).  We may be rounding up, however, which would assign
at least 1px extra to each column until we run out of extra width...

this looks like wfm with current trunk
