Well for now and until :booktabs t is incorporated this is what I
am using:
#+BEGIN_SRC emacs-lisp
(defun orgtbl-to-latex-booktabs (table params)
"Convert the Orgtbl mode TABLE to LaTeX using booktabs
package." (let* ((alignment (mapconcat (lambda (x) (if x "r"
"l"))
org-table-last-alignment ""))
(params2
(list
:tstart (concat "\\begin{tabular}{" alignment
"}\n\\toprule") :tend "\\bottomrule\n\\end{tabular}"
:lstart "" :lend " \\\\" :sep " & " :efmt "%s\\,(%s)"
:hline "\\midline")))
(orgtbl-to-generic table (org-combine-plists params2
params))))
(setq orgtbl-radio-table-templates
(delete-if (lambda (x) (equal (car x) 'latex-mode))
orgtbl-radio-table-templates))
(add-to-list 'orgtbl-radio-table-templates
'(latex-mode "% BEGIN RECEIVE ORGTBL %n\n% END
RECEIVE ORGTBL %n\n\\begin{comment}\n#+ORGTBL: SEND
%n orgtbl-to-latex-booktabs :splice nil :skip 0\n|
| |\n\\end{comment}\n"))
#+END_SRC
