Can you provide the full (setq org-capture-templates ...)
s-expression?

Did you tried this?

(setq org-capture-templates
 `(("f" "The template description" table-line
        (id ,some_variable)
        "this is the template content"
        :table-line-pos "II-1"
        :immediate-finish t)))

Yes, it expects a string.

See above.  The problem being, of course, that the capture template
for "f" will use some_variable *statically* -- if the value of the
some_variable variable changed after you evaluated the s-expression
(setq org-capture-templates ...) then the new value will not be
known.

What feature exactly?  To allow a function here that would dynamically
set the id?

If you want to use a function ,some_variable will not work, check 
,@ constructs in the Elisp manual.
