"Tables should not be used to position elements graphically. Tables used in this way, known as "layout tables", do not observe the implication of tabular data inherent in the term "table", and can create particular accessibility problems as described in the techniques that follow."

Unless of course you would argue the difference between "should not" and "not allowed", in which case I guess you would win.
