729114 - HTML Table column/cell width update regression

Status: RESOLVED DUPLICATE of bug 735579

(Core :: Layout: Tables, defect)

Description

[r.i.k]

Attachment: HTML + Javascript testcase

User Agent: Mozilla/5.0 (X11; Linux i686; rv:10.0.1) Gecko/20100101 Firefox/10.0.1
Build ID: 20120208060813

Steps to reproduce:

I build a TABLE with CSS "table-layout: fixed", contained in a DIV with fixed-height and scroll overflow. Each cell (ie.TD element) have CSS "white-space: nowrap", "overflow: hidden" and "text-overflow: ellipsis" (CSS3)

This bug is similar to #451876, but this last one is too old to be reopened, and the current one only applies to Firefox 10 (Win/Linux), as there's no trouble in Firefox 9 (Win/Linux).


Actual results:

When using javascript to modify columns widths (ie. COL elements), the rendered cells (related to the modified columns) is not correct.

In the supplied testcase, press first link, then second link, and then scroll the table.
The column (COL element) has been correctly resized, the cell edges did not align (see the TD background color for a visual proof).


Expected results:

The cells should have been aligned with their related column (left|right) edge.

Making table rows not be absolute containing blocks does NOT help here.

Mats, any idea what's going on?

Note that the fixed-height block containing the table _does_ seem to be necessary, by the way.

Hmm, I can't repro on trunk.  Is this fixed?

Comment 6

[Boris Zbarsky [:bzbarsky]]

Yep.  This looks like a dup of bug 735579 (complete with fixed-height div); that bug has a clear explanation of what was going on here.

Is it worth to create a reftest based on this?  (I can do that if you want)

Comment 8

[Boris Zbarsky [:bzbarsky]]

I checked one in in bug 735579, so probably no need for a second one.
