Subject: Re: How to add content from a file to a table automatically

Thank you Eric and Jambunathan for your answers.
If I process the whole table with babel to manually add the lines from the
external file than I would have to take care of updating the formula for
the "Total" value as well as making sure the new content was added before
the "Total" line, right?. The later is simple, but updating the formula
could be complicated.
Meanwhile, I'm investigating using org-capture for this.
For instance, if I use a template such as
#+begin_src emacs-lisp
("f" "test" table-line
(file+headline "test.org" "Test table")
(file "path/food.org")
:table-line-pos "II-1"
:immediate-finish t)
#+end_src
where the food.org file has a single line then I can capture with
#+begin_src emacs-lisp
(org-capture nil "f")'
#+end_src
and org-capture will place the content from the "food.org" file in a table
in the "Test Table" headline of the test.org file.
The advantage of using org-capture instead of pure babel is that it will
already put the content in the correct place and update the
formulas. However, the formulas are updated correctly only if I capture a
single line each time.
I think a combination of babel with org-capture is my best option.
Once that is working I will use your timer approach for automating this
(while I investigate inotify suggested by Jambunathan).
