When laying out a complex table with colspan > 1 and
overlapping chunks, the layout engine forces some columns to
a minimum size. This makes the resulting table much larger,
and less readable.
Reproducible: Always
Steps to Reproduce:
1. Display page included below, resize the window smaller than
the table.
2. repeat commenting out the row of
3. add a SIZE=5% to each of the middle columns in the   row.
this shows a more reasonable behavior (forced).
Actual Results: The second, fifth, and eighth columns are forced down to a
minimal size, which makes the table cumbersome.
Expected Results: The empty columns should be free floating in size so that the
table compacts reasonably.

Just reconfirming this, it's still happening. Here's another example. This should create a table with two rows; the first has four cells, each 100 pixels wide, and the second row should have 5 cells, offset by 5 pixels from the first row, ending up like this: |...|...|...|...| |.|...|...|...|.| The edge cells on the second row are half the width of all the other cells. This does not display properly as of 2002101508. Instead, the rightmost cell in BOTH rows is about 50 pixels wider than it should be. <TABLE border="0" cellpadding="0" cellspacing="0" width="400"> <TR> <TD colspan="2" width="100" bgcolor="#ff0000">a</TD> <TD colspan="2" width="100" bgcolor="#00ff00">b</TD> <TD colspan="2" width="100" bgcolor="#0000ff">c</TD> <TD colspan="2" width="100" bgcolor="#ffff00">d</TD> </TR> <TR> <TD colspan="1" width="50" bgcolor="#ff00ff">e</TD> <TD colspan="2" width="100" bgcolor="#00ffff">f</TD> <TD colspan="2" width="100" bgcolor="#bbbbbb">g</TD> <TD colspan="2" width="100" bgcolor="#444444">h</TD> <TD colspan="1" width="50" bgcolor="#666680">h</TD> </TR> </TABLE>

Test case demonstrating the code in description but in HTML 4.01 strict with CSS and also the table in comment #5. I added a button which append a colgroup node in the table; with such node added, the layout sizes of cells is correct. I also removed colspan="1" from both tables as this is the default number value for colspan. I also see/confirm a layout bug in XP Pro SP1, build 2003011713.

the bug doesn't depend width settings and is very cleary vizualized http://staff.csc.fi/pj/tmp/grafiikkaatyyleilla.html
I have a layout but that I think is the same bug. It seems to me that except for the extra first row, these two table should layout more or less the same. Instead the "virtual" second column in the first table is not given any width, while it lays out reasonably in the second table. <table border=1 style="background-color:#eeeeee;" bordercolor=black> <tr><td colspan=2>ONE ONE ONE ONE ONE ONE ONE</td><td>TWO</td></tr> <tr><td>THREE</td><td colspan=2>FOUR FOUR FOUR FOUR FOUR FOUR</td></tr> </table> <p> </p> <table border=1 style="background-color:#eeeeee;" bordercolor=black> <tr><td> </td><td> </td><td> </td></tr> <tr><td colspan=2>ONE ONE ONE ONE ONE ONE ONE</td><td>TWO</td></tr> <tr><td>THREE</td><td colspan=2>FOUR FOUR FOUR FOUR FOUR FOUR</td></tr> </table>

I think it may be from a core problem without any styling. Introduced in firefox 3.+ Here is a simplistic code example that shows it's not working correctly. Run this same html against Firefix 2.+ and it works as you would expect. Output should look like this: ROOT 1 SUBDATA 1 1 SUBDATA 1 1 1 SUBDATA Firefox 3.+ showing this: ROOT 1 SUBDATA 1 1 SUBDATA 1 1 1 SUBDATA HTML EXAMPLE: <HTML> <Body> <H3> COLSPAN - PROBLEM introduced in Firefox 3 </H3> <TABLE> <TR> <TD COLSPAN=20>ROOT</TD> </TR><TR> <TD>1</TD> <TD COLSPAN=20>SUBDATA</TD> </TR><TR> <TD>1</TD> <TD>1</TD> <TD COLSPAN=20>SUBDATA</TD> </TR><TR> <TD>1</TD> <TD>1</TD> <TD>1</TD> <TD COLSPAN=20>SUBDATA</TD> </TABLE> </BODY> </HTML>
