Status: RESOLVED DUPLICATE of bug 186317

(Core :: Layout: Tables, defect)

Compare the following two pages:

http://www.frostjedi.com/terra/scripts/demo/reversi/tables-collapse.html
http://www.frostjedi.com/terra/scripts/demo/reversi/tables-collapse2.html

Note the appearance of the second table on the first page in Firefox. The only difference between it and the first table is the border-collapse setting. Contrast this with the second page. Three tables, two border-collapse settings. The same two we saw on this page. Yet one of the border-collapse settings looks differently on that page then it does on this page.

In Internet Explorer, it's consistent for both pages.

Reproducible: Always

Attachment: HTML to demonstrate the problem

I've experienced the same problems, but have also noticed that the presence or absence of heading and/or data cells in the first table affect how those in the third are displayed.  This attachment is a standalone file that can be viewed in four different ways to demonstrate the problem: just click each of the links and see how the third table changes.

Sorry, didn't realise the attachment wouldn't retain its filename: save it as tables.html and then open it.

the code in comment 9 is already marked for removal see the patch for bug 43178, which is slowly moving trough review mills.
