I'd lobby for integration into the test framework.

Yes they are (by accident mostly as a side effect of how the table gets
imported), but only for Babel languages (except elisp) that can return
tables as values.  I only recently implemented the necessary processing
for Perl.  The returned string gets interpreted as a table if it is
multiline and/or has pipe symbol in it.  Normally the separator should
be a TAB character, but pipes work just the same (the actual
interpretation is done by org-table-convert-region, which also inserts
the leading "| " that Rick is complaining about).

If you want to have Org interpret the table the way Rick seems to want,
then the string must be a valid Org table that should be cycled after
insertion (type "org" or "wrap").  I think the only thing still missing
is interpreting "^[ \t]*|-" as hline.
