Yes, I look inside.

My use case is that Org buffer is used for presentation purpose, it is
not a file, it is generated buffer. This means tables cannot be
aligned before, but after, as the Org buffer does not exist before, it
exists only after rendering.

Then I look in the code by searching for variable
`org-startup-align-all-tables', and I find this within `define-derived-mode':

  (unless org-inhibit-startup
    (org-unmodified
     (when org-startup-with-beamer-mode (org-beamer-mode))
     (when (or org-startup-align-all-tables org-startup-shrink-all-tables)
       (org-table-map-tables
	(cond ((and org-startup-align-all-tables
		    org-startup-shrink-all-tables)
	       (lambda () (org-table-align) (org-table-shrink)))
	      (org-startup-align-all-tables #'org-table-align)
	      (t #'org-table-shrink))
	t))

And I think such larger definitions shall rather be split into smaller
useful functions.

For myself I have made this, which I need to additonally invoke via M-x then it works:

(defun rcd-org-table-align-all ()
  (interactive)
  (read-only-mode 0)
  (org-table-map-tables
   (lambda () (org-table-align) (org-table-shrink))
   t)
  (read-only-mode 1))

> #+STARTUP: align
> will align all the tables when opening an Org file.

And in this case I would like it on the end initialization, not
before. But problem is temporarily solved for Org mode by using M-x
rcd-org-table-align-all as my presentation buffer is in read only mode.

Org has nicer table in its source. Asciidoctor does not have, but then
Asciidoctor renders better PDF tables. So I am now using both
versions, Org and Asciidoctor.

⟦ (ignore (setq my-total 0)) ⟧
⟦ (ignore (defun my-add (n) (setq my-total (+ my-total n)) 
   (format "UGX %s" n))) ⟧

== Monthly Expenses

Would it be possible to put Org as Babel source, so that I have Org
table inside of Babel and cause Babel to render automatically on the
end of buffer rendering and invocation of org derived mode?
