Hi,

This patch enables user to applies a temporal TBLFM line where you are in.
It is useful when you switch a formula to another.
I hope you liked this.


When you have the following table,

    #+TBLNAME: test2
    | 1 | 2 |   |
    | 4 | 5 |   |
    | 7 | 8 | 9 |
    #+TBLFM: @1$3='(+ 10 7)
    #+TBLFM: @2$3='(+ 11 9)

hitting =C-c C-c= in the 2nd TBLFM line containg
"#+TBLFM: @2$3='(+ 11 9)" gives you this result:

    #+TBLNAME: test2
    | 1 | 2 |    |
    | 4 | 5 | 19 |
    | 7 | 8 |  9 |
    #+TBLFM: @1$3='(+ 10 7)
    #+TBLFM: @2$3='(+ 11 9)
