Status: RESOLVED WORKSFORME

(Core :: Layout: Tables, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051111 Firefox/1.5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

When a table is specified with table-layout: fixed, setting the visibility of a column to collapse either dynamically or right off of the page load has no effect. The example page contains a COL element with styling set to visibility: collapse, and clicking the "hide" text dynamically sets that styling but neither have any visible effect. 

Reproducible: Always

Actual Results:  
The columns were still visible.  Nothing happened and no errors were generated.

Expected Results:  
The columns should have been hidden from view.

Attachment: Simplified testcase

Thanks for reporting this bug.

For the future: a simplified testcase really means as simple as possible.  If you don't need scripts, get rid of them.  If you don't need extra columns, don't include them.  It's just confusing when the problem isn't instantly obvious, and the code the causes the problem is mixed with other irrelevant code.

(Confirming with current trunk.)

Hmm, seems to work with a current build; marking WORKSFORME.
