Why not? It's great.

Yeah, this is exactly what I do. I use the comment package to define a
comment environment called "orgtbl", which I then fold in
TeX-fold-env-spec-list (I guess LaTeX-fold-env-spec-list would be more
appropriate, but it works either way.)

There is one (small) disadvantage to this, so while we're on the
subject, I might as well make a feature request regarding TeX-fold-mode:
the problem is that although you can disable folding in comments that
start with %, it's not possible to disable folding inside comment
environments (either \begin{comment}...\end{comment} or user-defined
comment environments). Would it be possible to add that option? Also,
it'd be nice to have the option to disable folding in the preamble (or
even make that the default).

The reason for this request is that commands that are folded may occur
in the preamble and in #+ORGTBL lines without any argument. (In the
preamble in \newcommand definitions, for example), which leads to those
big ugly [Error: No content or function found] messages...

Anyway, just a nitpick, I know, but still... :-)
