Hmmm... but it should be solvable. Maybe something along the lines of
this (rough sketch, I have next to no experience with the org code
base):

#+begin_src emacs-lisp
(defun org-latex--table-newline (table-row info)
  (let ((next-el (org-export-get-next-element table-row info)))
    (concat "\\\\"
            (when (and next-el
                       (not (eq (org-element-property :type next-el) 'rule)))
              "\\relax")
            "\n")))
#+end_src

Until the next mail...,
Stefan.
