Nick's got a good editorial eye: "compatible options" is probably not
correct.  In the example on Worg hacks, \footnotesize is not an optional
argument to the \table environment, it is a LaTeX command whose scope is
determined by the \table environment within which it is issued.  So,
instead of "One can also pass other compatible options" it would be good
to say "One can also pass LaTeX commands into the \table environment" or
something along those lines.

The entry in Worg hacks looks good to me.  Thanks for taking care of
this, Suvayu.

Many thanks to Nick and Suvayu for figuring out how to get inside the
table environment from Org-mode.  I can't remember how many times I
tried and failed to figure this out on my own ...

All the best,
Thomas S. Dye
