Nothing unwilling about it – I had been deliberately trying to generate a
table with macros in it as the result of a babel block.  These macros are
defined in the document, in order to encapsulate some fiddly typesetting
which recurs very commonly.

Shouldn’t this workflow be supported?

In any case, the point is broader: the orgtbl-* functions cannot cope
with macros in their input at all (not just in the context of babel).  I
think the programmatic interface to org tables ought to be composable
with macros.

Thanks,
