Hello!
When I use superscripts/subscripts in tables, they are incorrectly
exported to LaTeX -- the placement of math-mode marks ($), braces ({,
}) seems mixed up.
As an example an excerpt of my current laboratory book.
========================
| Calculation | Zn layers | E_tot [eV/atom] (new) |
(interpolated) | \Delta{}E_tot [meV/atom] |
|---------------------+-----------+----------------------+----------------+-------------------|
[...]
The energy difference \Delta{}E_tot seems [...]
========================
This gets exported as:
========================
\begin{center}
\begin{tabular}{lllll}
Calculation & Zn layers & E_tot [eV/atom] (new) & (interpolated) & \D\
elta\{}E_tot [meV/atom] \\
\hline
\end{tabular}
\end{center}
The energy difference $\Delta${}E$_{\mathrm{tot}}$ seems [\ldots{}]
========================
Outside the table it works as expected.
You can see 3 errors in the export of "\Delta{}E_tot" to latex in the table:
1. There are no $ marks. During PDF-Conversion this causes
"! Extra }, or forgotten $" messages.
2. The braces around the subscript are missing -- only the first
character thus is
recognized as a subscript by (pdf)latex.
3. For some reason, the opening brace after Delta is escaped.
The problem doesn't depend on the specific case of a LaTeX entity
before the subscript (i.e. \Delta{}). It occurs too throughout the
document for combinations like "E_gb", though of course the escaped
brace ( \{} ) doesn't occur there.
When explicitly writing "E_{tot}" in the table, this was exported as
"E_\{tot\}", which is just as unexpected.
I tested this with a freshly pulled version from the git repository
and with the org-mode sample above as the contents of a minimal file
with the same result.
king regards, Yu

I think you'll be happier with the new exporter: it does this correctly
I think, and if you find other problems, I'm sure Nicolas will be happy
to fix them.
At the risk of putting words into Bastien's mouth, I would say that at
this point, the old latex exporter should probably be considered
unmaintained: nobody is putting much time into it.
To use the new exporter, see a post of mine from a couple of days ago:

HTH,
