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

You may want to use something like this, (I knew the syntax for ~"$1"~
and used the formula debugger ~C-c {~ to find the syntax for
~"(Smith)"~):
| name | C1 | C2 | Res |
|--------+----+----+-----|
| Smith | 9 | 1 | 1.7 |
| Miller | 6 | 2 | 8 |
| Adams | 5 | 5 | 10 |
#+TBLFM: $4 = if("$1" == "(Smith)", 0.1 * $2 + 0.8 * $3, $3 + $2)

Ha, of course, thanks, why did that occur to me? I am bit surprised by
the () in Smith, should "Smith" not be sufficient? But it is not indeed,
how odd?
Anyhow, thanks a lot.

Indeed, this looks very weird. It has to do with the fact that table
formulas usually deal with numbers and expressions and not with strings.
When replacing $1 in a calc formula, Org adds parenthesis to allow also
algebraic expressions in such formulas. Consider the following case:
| 2 | 2+3 | 10 |
#+TBLFM: $3=$1*$2
This formula needs to be interpreted as 2 * (2+3). Without the
parenthesis, it would be read as 2*2+3, which is 7, not 10.
Basically, we need to make sure that whatever is in the field is
interpreted as one entity and not ripped apart by the operator precedence
in calc. And therefore, indeed, if you want to compare strings, you need
to add the odd-looking parenthesis inside the double quotes.
I guess we should document this. For lisp formulas, I did document the
variable interpolation, but apparently not for calc syntax.
I will put this into the manual.
