See [[http://orgmode.org/org.html#The-spreadsheet][Spreadsheets]]. ,-------------------------------- | * My Trip | :PROPERTIES: | :people: 4 | :END: | | | item | factor | total | | |------------+--------+-------| | | toothbrush | 1 | 4 | | | socks | 4 | 16 | | #+TBLFM: $3=$2*$PROP_people `-------------------------------- -- cheers, Thorsten
