No, the column names are fixed, so that's perfect, thank you. I
suspected there might be some more straight-forward way than the
interesting, but slightly more involved methods suggested by Achim and
Rasmus.
However, it is good have some examples for ":results raw" and ":post"
and I shall certainly be looking into "Library of Babel", as I seem to
be sliding gradually into programming in Org.
Cheers,
Loris
