I'm not sure I understand the example. You have two otherwise identical
tables, with and without rownames. And then you assign them to two
variables, WITHOUT_COLNAMES and WITH_COLNAMES. Do you mean
WITHOUT_ROWNAMES and WITH_ROWNAMES ?

If so, is your problem how to include or exclude the rownames when you
assign the table to the respective variables?

If so, I don't think it can be done with per-document global settings
using +PROPERTY lines.

Also, I think (?) that Eric's suggestion to index into the data wouldn't
work, because however you slice the data, the issue is not what ends up
as the leftmost column, but whether R understands the leftmost column as
rownames or not. But I may be misunderstanding something here.

You can use the :header-args: property of an outline heading to set
:rownames yes or :rownames no for all the *src* blocks under that
heading, if that is a meaningful way to structure your document. Going
by your examples, though, it probably isn't.

It might be simpler to solve the problem in R rather than Org by
either adding or removing rownames as needed.
