Me again,
I would like to create a new DT with columns from another dt.
I have a DT (let’s call it dt_MAster) with a number of columns (see image)
I have to take only 4 columns (and the data that goes with it) to create another DT which must have the following form (see image).

Can someone tell me how to go about it please ?
