Excel Question :)

I have a column of numbers, and another column of numbers. How do I make them automatically line up with the matching number in the other column while having one column not shift. I also need the entire row moved when it finds a match not just that said number (confusing sounding i know :/)

Example:

Before:
1----2---40.00
3----7---37.00
7----3---24.00
2----1---67.00

After
1----1---67.00
3----3---24.00
7----7---37.00
2----2---40.00
