John,
Try this:
First, are there any fields above or below the first column in the row in question that have width that is greater? If so, that is the problem. Basically when you say "add to previous row" for a field, it will create a new column (in the table) and the result is this:
Long Field Above or Below | |
Field | Field Added to above row |
----------------------------------------------------
- TD Field width 200 -
--------------------------------------------------------------------------------------------------------
- TD Field width 100 (200) - TD Field width 100 -
--------------------------------------------------------------------------------------------------------
Also, if you don't set the width of the form, it will stretch to 100% and cause the fields added to the previous row to spread out to 100%
