Now I'd like to do more calculations based on the rows in the sum(Chars)
and sum(Lines) columns.

The new version of Aggregate supports adding new columns in the aggregated table. This can be achieved in two ways:- the :formula parameter adds a spreadsheet formula to the aggregated table- a #+TBLFM: line in the aggregated table survives refreshes.Documentation here: https://github.com/tbanel/orgaggregate#spreadsheet-formulasThis feature was borrowed from the "clock table" http://orgmode.org/manual/The-clock-table.html

Thanks to Michael Brand for pointing to it.
