Related to using the proper URL in the doctype, IE 6 renders table content as centered
when wrapping the table with center tag. The article explains when this happens and how to work around the problem.

We have found using the center tag to be far more problematic than the div align usage of center. (Yes, we have to support "older" browsers at work).
