Repeating <thead> and <tfoot> on every page with border-collapse: collapse

[SimonSapin]

Table border collapsing is annoying to do when header and footer row groups are repeated on every page. We should still do it. Later.

    # XXX For now table headers and footers in the collapsing border model
    # are not repeated on every page.

Hi. Is there a way to turn off repeating <thead> and <tfoot> on every page?

[SimonSapin]

@mzu Repeating on every page is the only real difference <thead> and <tfoot> have with <tbody>, so you could just use <tbody>. Or, if you’d rather not change the markup for some reason, use the following CSS:

thead, tfoot { display: table-row-group }

@SimonSapin Great, thanks.

@mzu how did you show/ repeat headers and footers on each page??

Sorry to necropost, I've had to remind myself of this multiple times, so to answer @NailaAkbar00 's question:

If you want table headers to repeat, it's sufficient to wrap the rows you wish to repeat in a thead tag.

<!-- Contents of thead is repeated on every page by Weasyprint.  -->

<!-- Default CSS includes: -->
<!-- thead { display: table-header-group; } -->

<table>
    <thead>
        <tr>
            <th>Country</th><th>Capital</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>France</td><td>Paris</td>
        </tr>
        <tr>
            <td>Germany</td><td>Berlin</td>
        </tr>
        <tr>
            <td>Italy</td><td>Rome</td>
        </tr>
    </tbody>
</table>


<!-- If for some reason, you don't want thead to be repeated on every page, you can use the following CSS rule: -->
<!-- thead { display: table-row-group; } -->
