Extracting Deltas between two tables serialized samples for multiple parametric measurements

[#1]

I have measured data for 50 serialized parts over three different temperature (Room, Hot, Cold) in three different tables.  Each serialized part has over 100 measured parameters.  I want to extract the deltas (Room - Hot) and (Room - Cold).  Putting these two calculations into two new tables would allow me to find the parts with the worst temperature deltas.

i have tried Table compare, but it does not output the deltas.

I am using JMP17

Stack your tables, join then together, perform the calculations and split the data gain to get the final delta columns

I was reading about stacking tables this morning and it appears that it would create additional columns in my already large tables.  Is there another way?

How familiar are you with JSL?
