calculation

I have generating some table for a html page.
I try to print a footer and a header every page.
The html code is generated dynamically by some java code. what's the best way to keep track of the no of row or how much i have printed in order to put a footer there? (counting the number of <tr>? number of <br>?) doesn't sound work.
any suggestion? thanks!

the best idea could be to have three tables,
1st table - header
2nd table - data from java code
3rd table - footer
now you don't have to worry about tr,td countings on a whole

thanks Balaji,
but i have no idea how long is the data for the content, but i know the header and footer, so what i need to do is counting the number of tr in the content? thanks!
