Aloha Rainer,

Perhaps this will work?  Eric Schulte wrote a function to make a LaTeX  
table out of an Org-mode table.  You should be able to call it from  
within a LaTeX source block that tangles to a suitably named file.   
There is an added benefit in the support for booktabs rules, so you'll  
need to have the booktabs package installed.

hth,
Tom
