Hi Henri-Paul,

You could define another code block which could be used to take just the
last line of the output, e.g.,

#+source: stuff
#+begin_src sh
  echo 1
  echo 2
  echo 3
#+end_src

#+source: last-of-stuff
#+begin_src sh :var input=stuff
  echo "$input" |tail -1
#+end_src

| one |
| two |
| 3   |
#+TBLFM: @3$1='(sbe last-of-stuff)

Hope this helps -- Eric
