Hello, I'm trying to figure out how to tell org that the first row of a src
block result is a table header.

from readthedocs
<https://org-babel.readthedocs.io/en/latest/header-args/#colnames> it looks
like ":colnames yes" should do this, but I haven't been able to get it to
work, and the code
<https://code.orgmode.org/bzg/org-mode/src/master/lisp/ob-core.el#L1671>
doesn't appear to want that to happen. maybe that is special handling for R
<https://code.orgmode.org/bzg/org-mode/src/master/lisp/ob-R.el#L164>.

#+BEGIN_SRC elisp :colnames yes
  '((one two) (1 3) (1 6))
#+END_SRC

I'm expecting an hline in the output but do not find one.

I know ":colnames '(one two)" works, but I don't know the header value
until I've generated the table.

Would this work for you?

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC elisp :colnames yes
 '((one two) hline (1 3) (1 6))
#+END_SRC

#+RESULTS:
| one | two |
|-----+-----|
|   1 |   3 |
|   1 |   6 |

--8<---------------cut here---------------end--------------->8---

I figured out that inserting `hline' works for some languages.  consistent
behavior with ":colnames yes" would be ideal but this solves my problem.

#+BEGIN_SRC elisp
  '((one two) hline (1 3) (1 6))
#+END_SRC

Yes, that works. Thanks.
