Issue Summary

Fixed width table with merged header column does not work as expected when changing width via UI.

--added 2013/03/14
Not only merged header column, if there are merged cells in body, this problem happens as well.

– added 2013/04/11
Problem also noticed without having to merge columns or cells

This is reproducible on Data Center: (yes)

Steps to Reproduce

1. Create a 3-column (A, B, C1/C2) table with 2 row headers(A and B get merged, and keep C separated as C1 and C2). See detail in fixed_width_table_change_width.txt
2. Confirm or change the table to 'Fixed width'
3. Put mouse on the line between B and C, increase the width of B column.

Expected Results

Only the width of B column changed, other columns won't get impated.

Actual Results

At least, the width of A column get impacted.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
