You can slice a single table full of calculations in different ways
into separate destinations. Or you can format the table differently.
There are many fun and exciting possible uses.
A fancier implementation would scan the document *once* for the
set of destinations. That could help implement another function
to update all destinations from all sources.
Refactor orgtbl-to-generic; explicitly separate heading from body.
Support last-line specializers.
Allow functions for some orgtbl parameters.
Add a :remove-nil-lines parameter to orgtbl-to-generic.
