Repeat <thead> on different pages

Hi all,
is possible repeat the <thead> in a table when the PDF divides the table on different pages?
This is my code:

<thead style="display:table-header-group;">
        <tr>
            <th colspan="9">Main Title</th>
        </tr>
        <tr>
           <th colspan="3">Title 1</th>
           <th colspan="6">Title 1</th>
        </tr>
        <tr> 
           <th align="center">Title 2</th>
           <th align="center">Title 2</th>
           <th align="center">Title 2</th>
	   <th align="center">Title 2</th>
	   <th align="center">Title 2</th>
           <th align="center">Title 2</th>
           <th align="center">Title 2</th>
           <th align="center">Title 2</th>
           <th align="center">Title 2</th>
         </tr>
    </thead>
    <tbody>
           <tr><td>..........</td></tr> 
    </tbody>

Thanks for Help :-)

This is not supported at the moment, sorry.
