That page shows that the Fisher Exact test can be implemented on tables 
with any numbers of rows and columns (so long as there are at least two 
rows and two columns).  Your biostatistician just didn't happen to know 
about this, but s/he shouldn't have been adamant when s/he was wrong. 
Show your biostatistician the MathWorld page.
