Re: [Orgmode] Advanced table

[Eric Schulte]

Hi,

Using Org-babel the following source-code block could prove at least a
partial solution.

--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp
  (let ((total 0) (responding t) purchases)
    (while responding
      (setq purchases
            (cons
             (list ""
                   (read-from-minibuffer "What: ")
                   (read-from-minibuffer "Where: ")
                   (read-minibuffer "How Much: "))
             purchases))
      (setq responding (y-or-n-p "more? ")))
    (append 
     purchases
     (list
      (list
       (format-time-string "%Y-%m-%d" (current-time))
       "" "" (progn
               (mapc (lambda (purchase)
                       (setq total (+ total (fourth purchase))))
                     purchases)
               total)))))
#+end_src
--8<---------------cut here---------------end--------------->8---

With Org-babel loaded, simply evaluate the block (press C-c C-c with the
cursor on/in the block) and the desired table portion will be placed
into your Org-mode file.  At the moment I can't recall how to remove the
quotes from the strings, but it should certainly be doable.

with slight modification it would also be possible to append the table
to an existing table, etc...
