Column Custom Formula
I would like to add a new column 'Vth' in my table with the following calculation:-First I need to find the index i of column 'Id' where the 'Id' is nearest to 1e-6; and then Vth = Vg(i). It should be grouped by Mod and Device columns as well. That is, each unique combination of Mod and Device will have one Vth value.
