works incorrectly for me (Org 8.2.7c from ELPA, Emacs 24.3,
Win7): C-c C-c on the #+TBLFM line updates four cells
(@2$1, @2$2, @3$1, @3$2) instead of one (expected response:
update of @2$2 only).

  I crafted a tiny change for my org-table.el to assign 1x1 cell
addresses "@I$2", "@III-2$4"... in the left-hand side of table formulae. 
The diff file is attached here:
