I understand that this particular use case is confusing, however there
are competing use cases and the case described here is not the most
common.
Take for example the following.
#+name: data
| header |
|--------|
| one |
| two |
|--------|
| three |
#+BEGIN_SRC sh :var in=data
echo "$in"
#+END_SRC
#+RESULTS:
| header |
| one |
| two |
| three |
In fact, hlines are *not* preserved by default with regular code blocks.
And in practice only emacs-lisp code blocks tend to create hlines
themselves. In general babel does a good deal of hline and colnames
processing.
#+name: with-a-header
| numbers |
|---------|
| one |
| two |
| three |
| four |
Strips both the header *and* the top hline by default.
#+begin_src emacs-lisp :var in=with-a-header
(mapcar (lambda (row) (mapcar #'length row)) in)
#+end_src
#+RESULTS:
| 3 |
| 3 |
| 5 |
| 4 |
Applies the code block only to the body of the input table.
#+begin_src emacs-lisp :var in=with-a-header :colnames yes
(mapcar (lambda (row) (mapcar #'length row)) in)
#+end_src
#+RESULTS:
| numbers |
|---------|
| 3 |
| 3 |
| 5 |
| 4 |
Perhaps we should change `org-babel-default-inline-header-args' to
include `(:hlines "yes")'. If there is no push back on that change I'd
be happy to make it.
