Instead of using save-excursion macro, it saves current point to a var,

and restore the point after execute org-table-align.

That would cause point move visually. Although the (point) value not changed, org-table-align function shall insert  spaces in front of the point. 

Don't know if it has already fixed, or there are some other concerns.

(defun +org-realign-table-maybe-h ()

  "Auto-align table under cursor."

    (let ((pt (point))

          (inhibit-message t))

      (if org-table-may-need-update (org-table-align))

      (goto-char pt))))
