Please see my attached example file. I wonder if it is easily possible to calculate the average of two time formatted (hh:mm) columns. Do you know how I can express that with the :COLUMNS: attribute? If that is not possible, do you know how to express that as a #+TBLFM: specification? Any help is appreciated. -- Sincerely yours, Martin Thorsen Ranang
