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
