How to create column headings in the output in SAP ABAP

Hi,

I am new to ABAP and I would like to know, how I can create column headings in the output of any program developed in SAP ABAP?

I know how to use header and footers but for ex if there are 6 fields/columns in the output, how can I keep headings for those columns. Please illustrate the process with steps and example if any. That will be really helpful.

Thanks,

Hari
