TABLES: aesthetics on columns

TABLES: aesthetics on columns

[Daniel Martins]

I have two questions on (possibly) improving aesthetics on columns
when editing org tables.

Following the thread on table editing, I have a minor issue with
editing org-mode for Latex generation (which I do most of the time!).
I have a table with several columns which are e.g. integer numbers and
the headings are single variables such as
a,b,c, M,k etc
it is OK but I want to include sometimes Greek terms and subscripts such as
\lambda or
$\delta_\kappa$
and the columns are not so nice to see and edit due to the different spacings


In Latex I could use \def

\def\ll{$\lambda$}
\def\dk{$\delta_\kappa$}


and the use \ll and \dk on the headings is quite nice (despite the
generally horrendous aspect of Latex tables when compared with the
clean, neat, simple and effective counterpart in org-mode).

So I have the first question:

1) Can I do the same in org-mode i.e. a previous (and possibly local)
definition or long variable befopre putting them in a table?


The other (maybe superfluous) question is

2) Can I locally define a table as completely in math mode?

So I could type e.g.


A)
|---+---+---+---|
|   | M | l | k |
|---+---+---+---|
| M | - |   |   |
| l |   | - |   |
| k |   |   | - |
|---+---+---+---|

Instead of

B)
|-----+-----+-----+-----|
|     | $M$ | $l$ | $k$ |
|-----+-----+-----+-----|
| $M$ | -   |     |     |
| $l$ |     | -   |     |
| $k$ |     |     | -   |
|-----+-----+-----+-----|

and when I export a table like A) to Latex I have the aspect of B) instead?

Try this in the header of the org file:

#+LATEX_HEADER: \def\ll{$\lambda$}

Sorry, I don't think this is possible.

Open source is the future. It sets us free.

Worked perfectly.

Question 2 is a (minor) pity.

Thank you very much.

with a header of
#+LATEX_HEADER: \newcolumntype{m}{>{$}l<{$}}
(where you define a new type of column, which always puts a $ to the
beginning and to the end of a cell)

and
#+ATTR_LATEX: align=mmmm   ( <- one m for each column )
directly above your table (this sets the mandatory argument for the
tabular environment, so that the new column type is used for every
column)

should probably do it, if i understand everything correctly.
