If someone could help me with this that would be great if it's even posible.

I have 2 colums as shown below:

123 156
125 256
256 359
365 598
458 875
875 890
923 950

I would like to sort and increment the numbers down in order as shown below:

123
125
156
256 256
359
365
458
598
875 875
890
923
950

Like numbers would be on the same line, different number would be
numerically incremented in order in the colums they are in.

Thanks for help in advance
Bob
