Does this sound reasonable?

Does anyone see clearly how to implement this?  (I don't.)

I  always wondered the same about other org-table-* bindings in org.el.

This works:

diff --git a/lisp/org.el b/lisp/org.el

 (org-defkey org-mode-map "\C-c="    'org-table-eval-formula)
 (org-defkey org-mode-map "\C-c'"    'org-edit-special)

I actually do this for org-table-* bindings in my config:

    ;; Bind the "org-table-*" command ONLY when the point is in an Org table.
    ;; http://emacs.stackexchange.com/a/22457/115
     :map org-mode-map
     :filter (org-at-table-p)
     ("C-c ?" . org-table-field-info)
     ("C-c SPC" . org-table-blank-field)
     ("C-c +" . org-table-sum)
     ("C-c =" . org-table-eval-formula)
     ("C-c `" . org-table-edit-field)
     ("C-#" . org-table-rotate-recalc-marks)
     ("C-c }" . org-table-toggle-coordinate-overlays)
     ("C-c {" . org-table-toggle-formula-debugger))
