[PATCH] Add support for `ltablex'

[PATCH] Add support for `ltablex'

[Francesco Pizzolante]

Hello,

Please find here a patch to support the tabularx table environment when used
in conjunction with the ltablex LaTeX package.

ltablex combines the advantages of longtable and tabularx packages: it enables
splitting of table across pages, and have fixed-width tables with
auto-adjusted columns.

Like longtable, it does not require a float table environment around.

I added a ltablex environment name which will be exported as a tabularx LaTeX
environment without a table float environment (this is the exact same behavior
as for longtable).

Usage is the same as tabularx (except that you use ltablex as :environment
name in the ATTR_LATEX specification):

- you need to specify a :width attribute, and
- an :align attribute.

In this case, like for longtable, the :float attribute is also ignored.

Best regards,
 Francesco

Thanks for the patch.

What are its advantages over "longtabu" environment, which is already
supported? There is a lot of table related packages, I'm not sure we
want to support them all.

I wasn't aware about the tabu package and its tabu and longtabu environments.
I'll try to use it and see if I can get what I want.

One nice thing about ltablex is that you don't need to use different
environments for short or long tables: you still use the well known tabularx
environment in any case.

For now, please ignore my patch unless I come up with issues using the tabu
package.

Thanks a lot for your answer.

 Francesco
