Bug 7264 – tables with rowspans don't display correctly

• Component: Tables
• Status: RESOLVED CONFIGURATION CHANGED

[David Glasser]

See the linked URL. The table should look roughly like:

+---+
|A|1|
| +-+
| |2|
+-+ |
|B| |
| +-+
| |3|
+-+-+

Specifically, the border between A and B should occur halfway through 2, not at its top.

FF (and apparently IE) render the table this way.  WebKit (including tonight's nightly) does not -- 2 and B get the same top.

Oddly enough, the values in Debug -> Show Render Tree show the B and 2 blocks as having different absolute y coordinates, which is correct, but not the same as what is actually drawn.

Reporter, could you add the testcase to the bug itself, for this case and all future bugs? That way we can add them to the patch if need be. Nice testcase though. I can confirm that our rendering differs from Firefox, Opera's rendering on the other hand is quite close to ours, with the line under A being only slightly lower then the line under 1. The reason that i'm confirming this is that Internet Explorer is closer to Firefox, the border bottom for A is just above halfway 2. None of the browsers seem to have the same opinion on how to render this however.

Thanks for your bugreport.

HTML file of table with rowspans that doesn't render how I'd guess it should

This bug seems is fixed on the latest webkit code. 
PS: FireFox renders the table exactly like the one shown in the description... However we render it similar to IE and Opera

This appears to work identically in Safari, Chrome, and Firefox.
