[patch] LaTeX export using tabu tables

[patch] LaTeX export using tabu tables

[Eric Abrahamsen]

[-- Attachment #1: Type: text/plain, Size: 1221 bytes --]

There are about forty different table environments for latex, all of
which do slightly different things, and none of them seem to do it all.
I found the "tabu" package recently, and thought "oh god another one",
but it seems to do it all: clever column alignment, longtable
functionality, all that good stuff.

Attached is a patch that lets you use the "tabu" and "longtabu" table
environments. Mostly the patch is necessary because tabu has its own
annoying syntax for table width declarations. Where everyone else does
something like:

\begin{tabular}{\textwidth}{cllr}

tabu does this:

\begin{tabu} to \textwidth {cllr}

Where you're allowed to use either "to" or "spread". Annoying, but in my
case still worth it. Since table plists can handle spaces, this works
with the attached patch:

#+ATTR_LATEX: :environment tabu :width to \textwidth :font \scriptsize :align rXrXrr

Actually I've just set `org-latex-default-table-environment' to tabu.

Dunno if this is worth it for other people, but there's the patch. If
access to the "spread" keyword isn't worth the trouble I can hard-code
"to": that would at least mean you could switch between table and tabu
without having to edit your ATTR_LATEX lines.

Yrs,
Eric

I think that would be better. Capability to switch between different
table environments should be important from a user's perspective.

Thanks for your patch. I didn't know about "tabu" package, but it looks
interesting.

I added some comments and suggestions wrt to the patch.

You could also add another attribute, :spread, which would used "spread"
instead of "to" when non-nil. This way, users can have the best of both
worlds.

That new attribute needs to be documented in the comments at the
beginning of the library.

You need to list each modified function in the commit message.

IMO, it's cleaner (as in more explicit) to use:

  (unless (member table-env '("longtable" "longtabu")) ...)

Ditto.

You may also use another branch in the `cond', in order to clearly
separate "tabu" and "longtabu" environments from other packages. It
would lead to some code duplication, but would allow for easier
development of tabu specific features (e.g. :spread keyword), if ever
needed.

See remark above.

It's definitely my new go-to table environment, though I'm struggling to
ignore the fact that it's got the ugliest documentation of any LaTeX
package I've ever seen.

I was trying to be too clever! Attached is a non-clever version that
includes a :spread keyword, and a (hopefully) correctly-written commit
message.

Thanks for the pointers,

Nice. A few more comments follow.

Actually the first line of the commit should be more general (and
shouldn't end with a full stop). Perhaps something like:

  ox-latex: Allow use of "tabu" table environment

I would drop a note about the "tabu" and "longtabu" support in the
description of the patch.

I think you mean (plist-get attr :spread), otherwise ":spread nil" will
still activate spread. Also, since it's a predicate, I suggest to name
the variable "spreadp".

"longtabu" gets its own cond branch, but not "tabu". I think that
defeats the purpose of the separation, which is to be able to add
support for features of this rich table environment without cluttering
the rest of the code. Doing it partially isn't worth the code
duplication it implies.

IOW, either we separate both "tabu" and "longtabu" completely, or we
separate none of them. Your call.


Thank you again.

Me being clever again -- I misunderstood how that would work.

I've kept the separation. There was no need to duplicate all the float
environment stuff, so there's not too much extra code.

Thanks for all the pointers!

Slightly off-topic: I've looked (briefly) into tabu's documentation,
and I agree;).  If you want your tables /beautiful/, however, I strongly
recommend checking out the booktabs package (its manual contains also
general aesthetical/typographical advice on tables!).

Best,

Isn't it ghastly? Works great though. I'm definitely using booktabs and
enjoying it. That's the nice thing about tabu, it does a good job of
using extend existing table packages (longtable, colortab, etc) rather
than rolling its own. I'm particularly pleased with the siunitx
integration -- it means I can get rid of a table filter that added
\num{NN} all over the place.

It looks good. I applied it.

Thank you for your work.

Well, that means that I'll have to look at tabu a bit closer (despite
the appalling look of the docs).  Thanks for the pointer!
