I think I almost have a working workflow.
What I need is a functionality to join either columns or rows of tables that are in different files. Here is what I have in mind for tables that are in the same file ** Columns #+NAME: T1 | col1 | col2 | | 1 | 2 | #+NAME: T2 | col3 | | 3 | #+BEGIN_SRC emacs-lisp :var t1=T1 t2=T2 (cl-mapcar #'append t1 t2) #+END_SRC #+RESULTS: | col1 | col2 | col3 | | 1 | 2 | 3 | ** Rows #+BEGIN_SRC emacs-lisp :var t1=T1 t2=T2 (append t1 t2) #+END_SRC #+RESULTS: | col1 | col2 | | 1 | 2 | | col3 | | | 3 | | Now the 3rd package orgtbl-aggregate allows me to aggerate column of tables that are in different files, via an ID generated via org-id-get-create and saved via org-id-update-id-locations as in #+BEGIN: aggregate :table "uwe" :cols "Level" #+END: Where the table uwe is located in a different file. However it seems only to work for one table at the time, so if you have 20 tables in 20 files that a bit complicated Any idea how to append column or rows from different table in different files in one go?
