[O] table, calc, reorder and protect calculation in one cell

[Uwe Brauer]

Hi

I have the following problem

This is my original table

The row starting with smith is calculated differently from the other two

* Orginal

#+begin_src 
| name   | C1 | C2 | Res |
|--------+----+----+-----|
| Adams  |  5 |  5 |  10 |
| Miller |  6 |  2 |   8 |
| Smith  |  9 |  1 | 1.7 |
,#+TBLFM: $4=$3+$2::@4$4=0.1*@4$2+0.8*@4$3
#+end_src

Now I reorder the table using the column C1
* Original reordered
#+begin_src 
| name   | C1 | C2 | Res |
|--------+----+----+-----|
| Smith  |  9 |  1 |  10 |
| Miller |  6 |  2 |   8 |
| Adams  |  5 |  5 | 4.5 |
,#+TBLFM: $4=$3+$2::@4$4=0.1*@4$2+0.8*@4$3
#+end_src


Everything looks fine, however when I recalculate the table calc follows
its definition and I obtain 
* Original reordered recalculated

#+begin_src 
| name   | C1 | C2 | Res |
|--------+----+----+-----|
| Smith  |  9 |  1 |  10 |
| Miller |  6 |  2 |   8 |
| Adams  |  5 |  5 | 4.5 |
,#+TBLFM: $4=$3+$2::@4$4=0.1*@4$2+0.8*@4$3
#+end_src

Which is not what I want. So the question is this.
Is there any way to enhance the ordering of rows so that it is reflected
in the way the rows a calculated
I mean reordering should/could have produced

* Original reordered TBLFM changed

#+begin_src 
| name   | C1 | C2 | Res |
|--------+----+----+-----|
| Smith  |  9 |  1 |  10 |
| Miller |  6 |  2 |   8 |
| Adams  |  5 |  5 | 4.5 |
,#+TBLFM: $4=$3+$2::@2$4=0.1*@2$2+0.8*@2$3
#+end_src


Is this behavior possible? When I delete a row or a column, the  TBLFM
is updated, could that be done for reordering?

Thanks
