Hi Mozumder,
First, if you want keep accessing the most excellant resources at JavaRanch, you need to change your display name to a first and last name as is the JavaRanch policy.
Sun has an excellant tutorial at
How to Use Tables. So just go there and learn the basics. After that if you have any more specific questions, come back to the Ranch.
Hope this helps,
Michael Morris
