I want a table to be centered except I don't want the first column to be considered in the centering procedure. That is, I want columns 2 to N to be centered perfectly, and column 1 to be hanging off in the left margin.
I also want the table heading and text at the bottom of the table to be aligned with the 2nd column onwards (so clearly I don't want the heading/caption to begin from the left margin or the 1st column).
This is the table that I'm working with:
