Hi everyone.
I am using NSTableView and Core Data and would like to sum numbers
from two columns and show the sum in third column for every row. Like
this:

what is the easiest way to do this?
is there a way to do this in Table Column Bindings / Value
Transformers (like we do for @sum, @count, etc.) or maybe in
xcdatamodel?
thanks for help in advance!
