You can slice a single table full of calculations in different ways
into separate destinations. Or you can format the table differently.

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.
