Generate extra columns and its values based on two tables.

Hi All,

I need some help in doing a calculation based on two separate data sets. First data set has different values in different columns. And in 2nd table, there are three main character columns. Now based on a these three columns and based on matching other conditions, we need to perform subtraction operation in first table and results need to be store in a new column in first table.
Something like this -

Names Default to here(1);

dt1 = Data Table("Dataset");
dt2 = Data set("Realtime");

//Create R1 column in Table 1.
// In Table 1, Somehow find the matching values for board and sensor from Table 2 and perform the calculation from different columns
// Board == M & Sensor == 2 and C11 & C8 is not missing then R1 = C11 - C8, otherwise leave it empty
// Board == M & Sensor == A and C11 & C10 is not missing then R1 = C11 - C10, otherwise leave it empty
// and so on.
//Create R2 column in Table 1 and then calculate values
//
// Probably in first loop we can generate 8 columns from R1 to R8 and then calculate each value of these columns somehow.

Any help?

Hi HSS

I'm not sure the idea is what your want.

IMO, you could Inner Join the 't1' & 't2' which indexes are 'Board' & 'Sensor'. Then got a 't3'.

In 't3', create Col(R1) with formula(if(condition1&2&3&4, R1=C11-C8, else "Empty").
