Status: RESOLVED DUPLICATE of bug 217769

(Core :: Layout: Tables, defect)

Description

[Chris Rebert]

Attachment: Screenshots showing rendering differences

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36

Steps to reproduce:

1. In Firefox 30.0, go to http://jsfiddle.net/rZLCu/show/ or http://jsfiddle.net/rZLCu/


Actual results:

Out of all the borders set on the table and its cells, only the top border on the table itself seems to get displayed.


Expected results:

All the borders on the table and its cells should get displayed.


==Further info==
Click the "Add Row" button, and the borders will magically appear. Click the "Remove" button, and the borders will magically disappear again.

Attachment: Simplified test page (test.html).

Attached a more simplified test HTML page (also available on http://jsfiddle.net/dha36400/).
The problem only appears if there is an empty tbody, i.e. if empty tbody is removed (i.e. only thead and tfoot remain), the outer border is rendered correctly.
IMHO the outer border should be rendered regardless of a possibly empty tbody tag (as is done by other browsers).

Ok, this bug is really annoying. I can't believe, that this bug stays open since more than a year now, and nobody has fixed it.

HTML specs say, empty tbodies are allowed, but it seems, mozilla is ignoring that, and collapsed borders are not displayed.

PLEASE fix that ****!

https://github.com/w3c/csswg-test/pull/793 added tests for this to the CSS test suite.

FWIW, I gave mozregression a whirl.
This bug repros in OS X Firefox 4.0b7pre (2010-10-02 030833), and I couldn't get mozregression to run anything earlier than that.
So this bug isn't a regression and has probably always existed.

It's still happening with firefox-59.0.2-1.fc27.x86_64.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
