I've had the same problem when working with tables and ocaml, as the
latter requires everything in the table to have the same type, so I need
to make sure everything is a string. To work around this, I did the
following:

#+name: convert-table
#+BEGIN_SRC emacs-lisp :var data=tps
  (mapcar (lambda (row)
            (mapcar (lambda (cell)
                      (if
                          (numberp cell)
                          (number-to-string cell)
                        cell))
                    row))
          data)
#+END_SRC

#+BEGIN_SRC ocaml :var data=convert-table :results output raw
  (* ocaml code *)
#+END_SRC

Best,

Alan
