I use loop to generate multi tables.
There is a problem: only the first table generated from current R src.
can be aligned correctly, which sometime is very annoy.
The below hook can align all the tables generate from R code:
#+begin_src elisp
(add-hook 'org-babel-after-execute-hook 'eh-org-babel-align-tables)
(defun eh-org-babel-align-tables (&optional info)
"Align all tables in the result of the current source"
(interactive)
(let ((location (org-babel-where-is-src-block-result nil info)))
(when location
(save-excursion
(goto-char location)
(when (looking-at (concat org-babel-result-regexp ".*$"))
(while (< (point) (progn (forward-line 1) (org-babel-result-end)))
(when (org-at-table-p)
(toggle-truncate-lines 1)
(org-table-align)
(goto-char (org-table-end)))
(forward-line)))))))
#+end_src
