     now have the status of *functions*.

+Not only can Org-babel pass entire tables of data to source code
+blocks (see [[arguments-to-source-code-blocks]]), Org-babel can also be
+used to call source code blocks from *within* tables using the
+Org-mode's [[http://orgmode.org/manual/The-spreadsheet.html#The-spreadsheet][existing spreadsheet functionality]].

+In fact the functional test suite for Org-babel is implemented as a

+evaluate the table =C-u C-c C-c=, and all of the tests are run
+updating the table with pass/fail statistics.

   What about those source code blocks which are so useful you want to
   have them available in every org-mode buffer?
