insert itab1 into itab2 as a coloumn

Hi all,

can any one tell me how should i insert the contents of one internal table suppose IT1 as a single coloumn in another internal table IT2..

My IT1 has 4 fields.

data of these fields should come one below the other as a single coloumn.

I should insert this column in between the coloumns of IT2.

Thanks in advance.

Regards.
