Thanks, that works!

Since this works differently for org results and raw results, can you
explain whether I understand this correctly: a ":hlines yes" at the end
of the line is needed to keep hlines in the output of a #+CALL if the
result is in org-mode, but a ":hlines yes" is not needed if the output
is raw.

In fact, a ":hlines no" keeps hlines in raw output; see a summarizing
example below.

>From the documentation I got the impression that if hlines are pruned,
they are pruned from the _input_:

"The :hlines argument to a code block accepts the values yes or no, with
a default value of no.
- no Strips horizontal lines from the input table."
