Table control

Hi all,

here's my prob......

I am working with table control in a module pool program, i have got the data into my internal table, but

1. How to get that data from internal table to my table control.?

2. After creating the table control on the screen painter, as i click on activate, it shows an error that the table control is created without any columns.? what to do for that.?

If any one could explain me how to proceed, through algorithm or psuedo code.

Please do not give code samples. Detailed step by step explanation would help.....!!!!
