Hi Bastien,
First I created an org-mode file with the following content to act as the
target.
--8<---------------cut here---------------start------------->8---
* Test table
:PROPERTIES:
:ID: MyTestID
:END:
| | Nome | Valor |
|---+----------------+-------|
| | something | 12.00 |
| | something else | 23.45 |
|---+----------------+-------|
| # | Total | 35.45 |
#+TBLFM: @4$3=vsum(@2..@-1);%.2f
--8<---------------cut here---------------end--------------->8---
The capture template is something as simple as
--8<---------------cut here---------------start------------->8---
(setq org-capture-templates
'(
("f" "Add a new product and value")
("ff" "Table" table-line
(id "MyTestID")
"|| %^{Product} | %^{Value} |"
:table-line-pos "II-1"
:immediate-finish t)))
--8<---------------cut here---------------end--------------->8---
This works as expected, but for my use case each month the target should be
a different table (which I create with a different ID). Obviously manually
changing the capture template each month is error prone and easy to
forget. Therefore, tried to change the ID to a function providing the new
target or a variable. For instance the code below.
--8<---------------cut here---------------start------------->8---
(setq myIDVar "MyTestID")
(setq org-capture-templates
'(
("f" "Add a new product and value")
("ff" "Table" table-line
(id myIDVar)
"|| %^{Product} | %^{Value} |"
:table-line-pos "II-1"
:immediate-finish t)))
--8<---------------cut here---------------end--------------->8---
When I try to capture with this second template Emacs complains that it
cannot find the target ID "myIDVar". What I expected is that it would
search for the ID "MyTestID" that is the value of myIDVar and not for an ID
"myIDVar"
I have also tried the code below and it does not work either
--8<---------------cut here---------------start------------->8---
(defun some-function-return-the-id ()
"DOCSTRING"
(interactive)
"MyTestID")
(setq org-capture-templates
'(
("f" "Add a new product and value")
("ff" "Table" table-line
(id (some-function-return-the-id))
"|| %^{Product} | %^{Value} |"
:table-line-pos "II-1"
:immediate-finish t)))
--8<---------------cut here---------------end--------------->8---

This is something I'll have to keep in mind. However, I don't expect this
to be a problem since I start Emacs everyday. It is enough for me if I can
set the ID to a variable (before setting org-capture-templates) and it uses
the variable value as the ID, instead of trying to interpret the variable
name as the ID. In fact, even if I ever need to change the variable value
after org-capture-templates was set I'm fine by just reevaluating (setq
org-capture-templates ...) again so that it sees the new value.

Exactly. Simple using the value of whatever list object I put there. Be it
a variable value or a function that provides the. I'm fine if the value
provided by a variable or a function is only read when
org-capture-templates is set.

My lisp knowledge is very limited to what I have seen in my Emacs
initialization (and a lot of trying and error). But I have never seen "@"
used in lisp nor I know what terms to search for it..
