Hi,
 I had tried t but then removed it when it did not work and the documentation seemed to indicate that :booktabs was a toggle. 
I tried your suggestion to add  (setq org-e-latex-tables-booktabs t) to the .emacs file but I am still getiing \hline. I did make sure to get the latest version from git and I am running emacs 24.3.50.1.

Thanks.

Aloha RCY,

You can have this in your setup to enable booktabs globally:

  (setq org-e-latex-tables-booktabs t)

Or, you can give a table this attribute:

#+attr_latex: :booktabs t

I think your example should work if you add the t after :booktabs.

hth,
Tom
