How do I paste a column of text after a different column of text in Vim?

Question

I have two columns full of text, and I want to get them side-by-side. For example, I have

abc
def
ghi

and

123
456
789
         


        

Answer 1

Use visual block (ctrl-v) to cut the letter column. Then move to the first line of the number column. Move to the end and make one space. Then paste the letter column.
