Hi,
There is a small bug in the export to html code: It doesn't wrap header columns in <thead></thead>. This means that if you try print the table and it is a few pages long, it will not repeat the columns headers on each printed page. If you simply wrap the header with <thead></thead> and the body with <tbody></tbody> then it works as expected.
The correct table structure should look something like this:
<table>
<thead>
<tr>
<th></th>
</tr>
</thead>
<tbody>
<tr>
<td></td>
</tr>
</tbody>
</table>
