How to merge two columns in open office? For example i have the following datas in cloumns as follows.

A1 10 | B1 10

A2 11 | B2 20

A3 12 | B3 30

A4 13 | B4 40

Is it possible to merge these two columns into one. So that i should get the output like you see below,

A1 1010

A2 1120

A3 1230

A4 1340

Any help will be appreciated, thanks in advance.
