need a good method to Page break and add Header

Question

I am using itextsharp library.I design an HTML page and convert to PDF .
in that case some table are not split perfectly and row also not split correctly.
I tried to put a comment in the HTML code writing based on the font how many rows the page can contains, then after reaching the limit i just add another page,
this works but doesnt seems a professional way to fix this.

After a search i found many discussions using this code

<style type="text/css">
    table { page-break-inside:auto }
    tr    { page-break-inside:avoid; page-break-after:auto }
    thead { display:table-header-group }
    tfoot { display:table-footer-group }
</style>

But, what if i need to add a header on each page?
thanks
