Article text shifted very far to the right. The black spacer appears to be scaled way too much.

Reproducible: Always

Steps to Reproduce:
1.Go to page
2.
3.
Actual Results:  
Article text appears shifted to right.

Expected Results:  
Article text should fill most of the screen width as done in IE. Spacers on left side of orange border should be small instead of very large.

Default theme for all Firefox versions
Latest trunk was tried without any extensions and same result. Firefox 3.0.2 was tried with extensions Adblock Plus 0.7.5.5 and Nightly Tester Tools 2.0.2.

When Adblock was on the misalignment was much worse (shifted about double what it was before)

Both Firefox versions were tested and both had the same page misalignment. Have tried it on multiple computers with the same result (Intel PIII 500MHz, AMD X2-5600+, Intel Pentium M Mobile 2GHz maybe... all Windows XP).

This is what I see with the latest trunk build on windows: http://img211.imageshack.us/my.php?image=page2az4.png

Thanks for your reply. I think the screen resolution might need to be higher than you have it. The paragraph width looks about the same on my 24" but leaves the rest black (almost half screen). I would try minimum of 1280 x 960 resolution.

I can reproduce it on Vista also with firefox 3.0.1. I also ran through the standard diagnostic at the following link with no success. A clean reinstall didn't help.

http://kb.mozillazine.org/Standard_diagnostic_(Firefox)

I tested Portable Firefox 3.0.1, 2.0.0.16, 1.5.0.10, and 1.0.8 and only Firefox 3.0.1 presented the glitch.

Also be sure to maximize the browser. I can also reproduce this on linux (Ubuntu 8.04) and Mac with firefox 3.0.1.

I found where the bug appeared in the nightlies. See below.

Last nightly trunk that worked was at:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2006/12/2006-12-07-04-trunk/

first nightly trunk that didn't work was:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2006/12/2006-12-08-04-trunk/

I see indeed the problem on a high resolution Windows computer. 
That would mean that it is a regression from Bug 300030.

Attachment: reduced testcase

i am not certain why this should expand

Comment 10

[Bernd]

please notice that the first cell in the second column specifies 1px width
and the second cell is auto width but has a 100% width table inside.

Comment 11

I am a afraid that this relies on a old quirk http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/layout/tables/BasicTableLayoutStrategy.cpp&rev=3.228&mark=1068-1074#1060 

Please note that IE, webkit and opera overwrite the fixed width

please note: I am just triaging I am not in favour of this quirk

Its opening Pandora's box, I will not even start to think to implement without dbaron's blessing before, he just removed all those quirks that made the code so difficult to maintain.

[Bernd]

the letters are all one line in IE7, webkit and opera.

But if you reverse the order of the rows it changes in IE7 but not the others, right?
