Table border shown in wkhtmltopdf

[Peter Moser]

Hi,

I use WKHTMLTOPDF to generate a pdf. On my page, I have a table with no border. In the browser everything is fine. Example of table:

<table class="noborder" border="0">
    <tbody>
        <tr class="noborder">
            <th colspan="2" class="noborder">MyHeader</th>
         </tr>
     </tbody>
</table>

CSS: Noborder:

.noborder {
    border: 0px solid black;
}

But in the generated PDF there are the borders.

Version: wkhtmltopdf 0.12.4 (with patched qt)

Ubuntu 18

What am I doing wrong?

Best regards, 

Peter
