I am trying to achieve multicolumn cells in org-mode tables like in Multicolumn cells in org-mode tables, but with Latex inside the cells.
* Minimal Example
+------------+-----------+--------------+
| | \pi |
| +-------------+------------+
| |$\pi$ | |
+------------+----+--------+------+-----+
I found https://orgmode.org/manual/Tables-in-LaTeX-export.html and tried
#+ATTR_LATEX: :mode math
and
#+ATTR_LATEX: :mode math-inline
but no success.
The exported tex in the tex file is
$\backslash$pi
\$$\backslash$pi\$.
Can I protect the string in the cell? Is it possible?
