Hi Joe,
There is no way to map a code block over the rows of a table. You could
use the `sbe' macro and a spreadsheet formula to call a code block on
multiple table cells, but the results would be inserted back into the
table.
| A | -->A<-- |
| B | -->B<-- |
| eric | -->eric<-- |
| schulte | -->schulte<-- |
#+TBLFM: $2='(sbe foo (in $$1))
#+name: foo
#+begin_src emacs-lisp :var in="foo"
(format "-->%s<--" in)
#+end_src
Possibly you could use the sbe macro to simplify the elisp code block in
your example.
Best,
