How to add rows dynamically to in a JSPpage

Hi All,
I have a JSP page in which on the click of add button we have to add rows to the table .Can anyone tell and give me a small example of that.

Thanks

Dear,
JSP is used to display the content only where as the processing task should be done in Servlet.
After clicking add button request should pass to some servlet and then that servlet should prepare data to be display on the JSP page and redirect to JSP.

And second thing if u want to add in to current working page without refreshing the whole page you need to use other helping technology like:- AJAX.
