Hello,

This is my first patch so hopefully I followed the instructions correctly,

While using ~org-table-export~ on a table directly even with
~org-latex-tables-booktabs~ set to ~t~, it exports a normal table instead
of booktabs table. But on the same situation, if you export the whole
buffer the table will be exported according to booktabs.

So my theory was there is a discrepancy between the method used by
~org-latex-export-to-latex~ and the ~org-table-export~. And on browsing the
codes for those two I found this.

The code for ~org-latex-table-row~ used by latex export backend has this
line:

#+begin_src emacs-lisp :tangle yes
(booktabsp (if (plist-member attr :booktabs) (plist-get attr :booktabs)
     (plist-get info :latex-tables-booktabs)))
#+end_src

Shows that it also takes into account the ~info~ plist.


I couldn't find out what that info plist has, but I can assume it's the
information on the overall buffer or that table's context, and it has the
effect of using the booktabs from the config.

While the code for ~orgtbl-to-latex~ shows it only takes into account the
~booktabs~ parameter on latex table.

#+begin_src emacs-lisp :tangle yes
 :latex-tables-booktabs (plist-get params :booktabs)
#+end_src

So I tried changing the line in ~orgtbl-to-latex~ to

#+begin_src emacs-lisp :tangle yes
 :latex-tables-booktabs (if (plist-member params :booktabs) (plist-get
params :booktabs)
     org-latex-tables-booktabs)
#+end_src

So if there is ~booktabs~ parameter then it'll overwrite the settings but
if not it'll use the booktabs config.

There is probably a better way to use it, but this works for now so I tried
this.

Please find the attached patch with the fix.

Gaurav
