Bug: org-element does not recognize table.el tables [9.4 (release_9.4-53-g23f941 @ /home/nick/elisp/org-mode/lisp/)]

[Nick Dokos <ndokos@gmail.com>]

Consider an Org mode file with a table.el table (which I made by
first constructing an Org mode table and then usind `C-c ~' to convert it):


--8<---------------cut here---------------start------------->8---
* table.el table


  +----+----+----+
  |  a |  b |  c |
  +----+----+----+
  |  1 |  2 |  3 |
  +----+----+----+
  |  4 |  5 |  6 |
  +----+----+----+
  |  7 |  8 |  9 |
  +----+----+----+
  | 10 | 11 | 12 |
  +----+----+----+
--8<---------------cut here---------------end--------------->8---

Trying to export to LaTeX produces pretty mangled output.

It turns out that when in
 `org-latex-table', (org-element-property :type table) returns `org', so
 it thinks it's an Org mode table and calls `org-latex--org-table' to
 process it, producing output like this:

--8<---------------cut here---------------start------------->8---
\sout{----}----\sout{----}
\begin{center}
\begin{tabular}{lll}
a & b & c\\
\end{tabular}
\end{center}
\sout{----}----\sout{----}
\begin{center}
\begin{tabular}{rrr}
1 & 2 & 3\\
\end{tabular}
\end{center}
\sout{----}----\sout{----}

...

\begin{center}
\begin{tabular}{rrr}
10 & 11 & 12\\
\end{tabular}
\end{center}
\sout{----}----\sout{----}
--8<---------------cut here---------------end--------------->8---


Evaluating `(org-element-at-point)' returns `(paragraph ...)' all along
the top line and `(table (.... :type org ....))' when the cursor is at
the beginning of the `a b c' line.
