270438 - Table delete-column widget doesn't work for unusual cell array

Status: NEW

(Core :: DOM: Editor, defect, P5)

Description

[Mike Cowperthwaite]

Due to various tweaks using things like 'rowspan' you can get a table into a 
somewhat odd configuration where a cell has no neighbor in its column or row.  
When this happens, and the cell is selected, the row/column widgets don't work 
particularly well.

To reproduce:
1) In Composer, insert a 2x2 table.
2) Select the upper-left cell; using Properties, Advanced Edit, add an 
attribute:  rowspan = 2.  The table now looks like this:

+-----+-----+
+     +     +
+     +-----+-----+
+     +     +     +
+-----+-----+-----+

3) Select the bottom-right-most cell, the one that's sticking out.  The column 
widgets are shown on its top and left borders.
4) Click the (x) widget (delete row) on the top border.

Actual results:
No change

Expected results:
Cell is deleted.

There are other goofy things that can happen with these odd configurations, but 
this one is particularly annoying because it would be a simple way to "fix" the 
table after changing the 'rowspan' attribute.  

The workaround is to need to delete the cell via the menu.  However, in the mail 
composer, that option is buried under  Format|Table|Delete|Cell(s)  rather than 
being on the context menu.

I see this in Moz 1.8a5 Composer and MailNews, NVu 0.4, TB 0.9.

Can you reproduce with SeaMonkey v1.1.9 ?
(or Thunderbird v2.0.0.14 ?)
