I've been thinking about this some more.  We've had enough inquiries on
how to import tables from R or other programs and give it headers and
other decorations, maybe even formulas without having to construct the
table as Org syntax in the other language.  If we made such attributes
_table_ attributes (i.e. extend the table model of Org and not just some
decoration in the export) then this would become an easy thing to do.
So if a modification in this direction is in the cards, I certainly
support this proposal.  Defining a more user-friendly syntax for the
main features so that most of that complexity would be out of sight most
of the time shouldn't be too difficult.  It adds an extra step to the
normalization of tables before import/export, but the added
functionality should make up for that many times over.
