Here's a hyperbole-org integration that lets you use org-mode tables
outside of org-mode files. Shift-middle-click a "recalc" button and it will
recalculate the table right under it (this idea is from an old version of
the Oberon environment I wrote in Java, by the way).

Here's the code:

(defun bill/calc (end)
  (goto-char end)
  (re-search-forward "\n")
  (when (org-at-table-p)
    (org-table-analyze)
    (let* ((table-start (point))
           (rows (1- (length org-table-dlines)))
           (table-end (re-search-forward "\n" nil t rows))
           (inside (<= table-start action-key-depress-prev-point
table-end)))
      (when inside
        (goto-char action-key-depress-prev-point)
        (org-table-maybe-eval-formula))
      (goto-char table-start)
      (call-interactively 'org-table-recalculate)
      (org-table-align))))

(defib recalc ()
  "recalculate a table"
  (save-excursion
    (let* ((pos (point))
           (eol (progn (re-search-forward "\n") (point)))
           (bol (progn (re-search-backward "\n" nil t 2) (1+ (point))))
           (start (progn (goto-char pos) (re-search-backward "<" bol t)))
           (end (progn (goto-char pos) (re-search-forward ">" eol t))))
      ;;(message "pos: %s, prev: %s" (point) action-key-depress-prev-point)
      (and start end (string-match "<recalc[> ].*" (buffer-substring start
end))
           (hact 'bill/calc end)))))

Here's an example table you can put anywhere. Just shift-middle-click on it
to recalculate the org-mode table. Also, if you type a formula (and keep
the cursor on the same line) and then shift-click recalc, it'll handle the
formula:

<recalc>
| a | 12 |
| a |  5 |
#+TBLFM: @1$2=3*4::@2$2=2+3
