Elements relation on a matrice? Basic

Hello,

Is it possible to relate elements on a matrice? For exemple:

A = [20 1; 180 2; 135 3; 80 4]

If I want to sort the elements from the first collumn without changing its second collumn corresponding, is it possible?

I want it to end like:

B = [20 1; 80 4; 135 3; 180 2]

Thanks
