Not in one fell swoop, first sort the least significant etc
assume you would sort by columns A, B, C and D (in that order of
significance)
select C and sort in that order, then select A and sort by A
If the data requires 4 columns, A, I don't think you want to "select C and
sort" do you? That will uncouple the data in columns C and D from that in
columns A and B.
I think you mean to select columns A, sort on D (or C and D), then with A
still selected, sort on A, B, and C (or A and B). No?
