[O] exporting tables ignores empty lines in the tables

[Eric S Fraga]

Hello,

I have searched for a variable that may affect the following behaviour
but have not found one.  I have a table where I have intentionally left
a whole row empty (to be filled in by hand in a hard copy, say).
However, the table, when exported to latex/pdf, excludes any empty
lines.

For instance, this table

#+begin_src org
  | item     | cost |
  |----------+------|
  | stamp    | 65p  |
  |          |      |
  | envelope | 20p  |
#+end_src

generates the following latex:

#+begin_src latex
\begin{tabular}{ll}
 item      &  cost  \\
\hline
 stamp     &  65p   \\
 envelope  &  20p   \\
\end{tabular}
#+end_src

Can anybody point me in the right direction or is it not possible to
export (to latex) empty lines in tables?

Thanks,
eric
