I would agree there...we have an app that allows users to create forms
dynamically with a left and right panel section along with some full
width plug-in. At a minimum this is built with three nested tables.
Here's the really rotten part, the VP (original dev for the display
code) screwed a table close up somewhere. A bug they found literally
minutes before it when to prod at a client site, instead of giving me
15 minutes to trace it down, they wrapped the entire table structure
in another table to make it look pretty.

Drives me mental as it produces lots a visual screw up when a certain
pattern in the form elements is created
