How to retrieve data from Table Control

Hi,

I am a Beginner to ABAP. I want to know how to fetch the selected rows from Screen table control.

Here is my scenario:

I am having one table control with selection field. Once i select some rows means the selected rows are going to be stored in one Internal Table.

If any body knows the thing means please reply me the logic as well as giving me some code sample.

Thankyou.
