exporting tables + equations to latex

exporting tables + equations to latex

Hi everybody.

I like very much the orgtbl-mode for inserting tables in latex. It saves me
a lot of typing, and they are also quite beatiful to read in text, contrary
to plain latex tables.

The big problem I have is that I do not know how to put equations in cells.
In particular, I have this snippet of code in my latex file:

\begin{comment}
#+ORGTBL: SEND fp orgtbl-to-latex :splice t :skip 0
| Task     |  C |   T |   D | Prio | S_1 | $S_2$ | $S_3$ | $S_4$ | $B$ |
|----------+----+-----+-----+------+-----+-------+-------+-------+-----|
| $\tau_1$ |  2 |   8 |   6 |   10 |   1 |     0 |     0 |     0 |     |
| $\tau_2$ |  4 |  20 |  20 |    8 |   0 |     1 |     1 |     0 |     |
| $\tau_3$ | 10 |  50 |  40 |    6 |   0 |     0 |     3 |     1 |     |
| $\tau_4$ | 10 | 100 | 100 |    4 |   2 |     3 |     1 |     0 |     |
\end{comment}


which is exported as


\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|}\hline
% BEGIN RECEIVE ORGTBL fp
Task & C & T & D & Prio & \(S\_{}1\) & \(S\_{}2\) & \(S\_{}3\) & \(S\_{}4\)
& \(B\) \\
\hline
\(\tau\_{}1\) & 2 & 8 & 6 & 10 & 1 & 0 & 0 & 0 &  \\
\(\tau\_{}2\) & 4 & 20 & 20 & 8 & 0 & 1 & 1 & 0 &  \\
\(\tau\_{}3\) & 10 & 50 & 40 & 6 & 0 & 0 & 3 & 1 &  \\
\(\tau\_{}4\) & 10 & 100 & 100 & 4 & 2 & 3 & 1 & 0 &  \\
% END RECEIVE ORGTBL fp
\hline
\end{tabular}



which is NOT what I want: the underlines are translated as underlines, and
not as subscript command.


I also tried the following:

\begin{comment}
#+ORGTBL: SEND fp orgtbl-to-latex :splice t :skip 0 :fmt (6 "$%s$" 7 "$%s$"
8 "$%s$" 9 "$%s$")
| Task     |  C |   T |   D | Prio | S_1 | S_2 | S_3 | S_4 | B |
|----------+----+-----+-----+------+-----+-------+-------+-------+-----|
| $\tau_1$ |  2 |   8 |   6 |   10 |   1 |     0 |     0 |     0 |     |
| $\tau_2$ |  4 |  20 |  20 |    8 |   0 |     1 |     1 |     0 |     |
| $\tau_3$ | 10 |  50 |  40 |    6 |   0 |     0 |     3 |     1 |     |
| $\tau_4$ | 10 | 100 | 100 |    4 |   2 |     3 |     1 |     0 |     |
\end{comment}

and the solution is even worse:

\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|}\hline
% BEGIN RECEIVE ORGTBL fp
Task & C & T & D & $S$\backslash$\(_\)1$ & $S$\backslash$\(_\)2$ &
$S$\backslash$\(_\)3$ & $S$\backslash$\(_\)4$ & B \\
...
...
% END RECEIVE ORGTBL fp
\hline
\end{tabular}

Where is the \backslash coming from? I have no idea.
So, where is the problem? How can I put a simple mathematical symbol in a
org-mode table?


Thanks in advance

Radio tables have been rewritten in development branch, which will
become Org 8.3.

In this version, you will be able to achieve what you want using ":raw
t" parameter.

Try adding ":no-escape t" to the #+ORGTBL line

Thanks Nicolas and Jorge for your answers.

In my version (8.3beta-326-g6eb982.dirty taken from git):
- the :raw t flag does not work (same output as before)
- the :no-escape t works well.

After your answer, I understood this part is being reworked, so I decided
to update the org-mode git repository and now my version is
8.3beta-439-gfcce67.dirty. With this version

- with no special option, it produces the correct output
- with :raw t, the latex text is not traslated at all (empty cells)
- with :no-escape t, it produces the correct output

So, now I am all set, thanks a lot!!

This was a bug, which is now fixed. Thank you for noticing it.

> - with :no-escape t, it produces the correct output

:no-escape doesn't exist in the new implementation and is ignored. So it
boils down to providing no special option.
