Subject: How to execute Lisp code /after/ a capture template has been filled before it is finalized?

Hi,

I (want to) have a capture template that fills a table and
then (re-)calculates a cell based on a formula (and aligns
the table):

| - Note taken on %U \\\\
|   | Coin | Count
|   |-------+--------|
|   | 0.01 | %^{Number of € 0.01 coins|0} |
|   | 0.02 | %^{Number of € 0.02 coins|0} |
|   | 0.05 | %^{Number of € 0.05 coins|0} |
|   | 0.10 | %^{Number of € 0.10 coins|0} |
|   | 0.20 | %^{Number of € 0.20 coins|0} |
|   | 0.50 | %^{Number of € 0.50 coins|0} |
|   | 1.00 | %^{Number of € 1.00 coins|0} |
|   | 2.00 | %^{Number of € 2.00 coins|0} |
|   |-------+--------|
|   |      | |
|   #+TBLFM: @>$>=(@I$1..@II$1)*(@I$2..@II$2)

If I naively append "%(org-table-recalculate t)" to that
template, the expression gets evaluated immediately when I
start the capture and the text:

| %![Error: (user-error Not at a table)]

gets appended to the capture buffer /before/ I get prompted
for the first field.

Looking at the hooks for org-capture-mode, I also thought
about recalculating the table at finalizing the capture (*1)
and tried:

| %(progn (message "org-capture-prepare-finalize-hook = %S" org-capture-prepare-finalize-hook) (add-hook 'org-capture-prepare-finalize-hook (lambda nil (message "Hook called.")) 0 t) (message "org-capture-prepare-finalize-hook = %S" org-capture-prepare-finalize-hook) "")

but to my surprise, org-capture-prepare-finalize-hook is nil
prior to the add-hook call, has stored the function after
the add-hook call, but in the interactive capture buffer is
nil again (and no message is printed in *Messages*).

How can I evaluate Lisp code after all prompts have been
answered?

TIA,
Tim

(*1)   I would prefer not doing this, as in this case I
       could not see the result prior to finalizing.
