Test case for bug 60479 with the code showed in the description.
311 bytes, text/html
Details 
Table attached renders incorrectly because second row are not showed. IE 4&5
shows OK and NS4 shows incorrectly but better than mozilla.

Try this code on IE and you will see how it must to be rendered. getting rid of
LEFTMARGIN='0' TOPMARGIN='0' MARGINWIDTH='0' MARGINHEIGHT='0'
tags then mozilla renders OK

<HTML>
<BODY LEFTMARGIN='0' TOPMARGIN='0' MARGINWIDTH='0' MARGINHEIGHT='0'>
<TABLE BORDER='1' CELLSPACING='0' CELLPADDING='0' HEIGHT='100%' WIDTH='100%'>
<TR HEIGHT='100%'>
  <!-- The height on the td tag is necessary for NS4 compatibility -->
  TD HEIGHT='100%'>TOP ROW</TD>
</TR>
<TR HEIGHT='20'>
  <TD HEIGHT='20'>BOTTOM ROW</TD>
</TR>
</TABLE>
</BODY>
</HTML>
I forgotten this info:

Mozilla {Build ID: 2000111620}

This works for me. The only difference I see with IE is that Mozilla renders the
"Bottom Row" just under the "first screen". To view the "Bottom Row", I have to
scroll down a few. In, IE the Bottom Row is displayed inside the "first screen",
but everything else works just fine. The margin attributes do what they're
supposed to do. Removing these attributes just inserts a margin...
Fabian.
This should be marked as WFM because the given height for the first table cell
is 100% so the height is basically the window screen height (body).  The second
row is displayed at 20.  Forcing you to scroll below initial screen.  This is
what I would expect.

THe better way to code this would be setting something like row1-->95% and
row2-->5%.
Not really. Table height should constraint all inner row heights.
Fabbian Guisset says: To view the "Bottom Row", I have to
scroll down a few.
Yeah!! That's what the web programmer doesn't wants. With this code, browser
should render a table with 100% height. That is: with the current browser screen
height. Then it should render a row with height 100% of container. This is a
100% of the table height, but the code has another row with height 20 so the
height of first row should be reduced by 20.

Think about widths. This should be the same. Look at this code:
<TABLE WIDTH='100%'>
<TR>
<TD WIDTH='100%'>ROW 1</TD>
<TD WIDTH='20'>R2</TD>
</TR>
</TABLE>
I can see row2 at the right of the browser screen and I cannot need to scroll
right to see the second row. This allows to create table with a small column of
width 20 constrained to the right of the browser screen. Original bug code
allows to create a small row with width 20 constrained to the bottom of the
browser screen.
That's why this bug should not be marked as WFM.
Other commect to fabian...
You said: Removing these attributes just inserts a margin...
If you see at the first row height if you insert the
 TOPMARGIN='0' MARGINWIDTH='0' MARGINHEIGHT='0'
tags, first row height is full body height. When you put this tags, browser
insert the margin but first row height is less than previous example, and I can
see part of the second row.
Anyway, this should render correctly in both cases (like IE) because inheritance
should be maintained also with height attribute like browser does with width
attribute.


"Not really. Table height should constraint all inner row heights."
Where do you see this described in the w3 spec for overflows?

The problem is you set row1 height to 100% of the table height also set to 100%.
Any other content like row2 is overflowed.  Where does it say in the spec that
the way to handle the overflowing is to reduce the first row?

I have come to understanding that just because IE renders it one way does not
make it correct way.

Mozilla is rendering this "correct" given the poor page design.
OK. You're right. On http://www.w3.org/TR/REC-CSS2/tables.html
 Section 17.5.3 (Tables - CSS2 specification) W3C says:
CSS2 does not define what percentage values of 'height' refer to when specified
for table rows and row groups.

I've said the IE example just like and example but I'm not a M$ supporter. I
think that Mozilla should render rows and columns with the same algorithm.
I've enclosed before a sample with rows and not mozilla, NS4 or IE renders the
row at the right of the browser visible window.

I assume that my code is not proper. So, please help me to implement what I want.

I would like an web page with a taskbar of 20 pixels at the bottom of the
browser window and web content on the main row. When I resize the browser, my
taskbar should remain at the bottom of the browser window and the main content
can reflow. Please help me!!!

Hi Mozilla guys, have you any comment about this bug?
Marking WONTFIX because of the already stated comments above.

If you need help rendering your page as desired try a newsgroup.  There are many
NG's that will be very helpful :-)  Thanks.

I think making this as RESOLVED is not a proper solution. But I assume it. 
Maybe when you have less bugs you can have time to solve this.
