Hi Eric,
The `sbe' macro can be used to evaluate code blocks in table formula.
For Example:
| 1 |
| 2 |
| 3 |
| 4 |
| 5 |
| 6 |
| 3.5 |
#+TBLFM: @7$1='(sbe mean (lst @1..@6))
#+source: mean
#+begin_src emacs-lisp :var lst=()
(let ((num (car lst)) (nums (cdr lst)))
(/ (float (+ num (apply #'+ nums))) (1+ (length nums))))
#+end_src
See the documentation string of this macro for more information.
Best -- Eric
