Hi
Is the a simple way to tell a org-table that
it adds say two columns in a certain way $4=0.2*($2+$3)
but only for certain values of the row. I hoped that
a hline would help but it does not the row containing Taylor
is treated in the same way as row 1 to 4.
| Row | Name | E1 | E2 | Res |
|-----+--------+----+----+-----|
| 1 | Smith | 1 | 2 | 0.6 |
| 2 | Miller | 2 | 1 | 0.6 |
| 3 | Meyer | 1 | 4 | 1. |
| 4 | Wilson | 2 | 1 | 0.6 |
|-----+--------+----+----+-----|
| 5 | Taylor | 1 | 2 | 0.6 |
|-----+--------+----+----+-----|
#+TBLFM: $1=@#-1::$5=0.2*($3+$4)
So what is the most comfortable to obtain what I want?
Thanks
Uwe Brauer

Depending on what you want you can use $5 = if($1 != 5, 0.2*($3+$4),
string("")). See also some other examples with if in the Org manual.

This seems to work:
--8<---------------cut here---------------end--------------->8---
#+TBLFM: $1=@#-1::@2$5..@5$5=0.2*($3+$4)
--8<---------------cut here---------------end--------------->8---
