PB_TABLE_HEADER_NOT_REPEATING

What happened

A table spans multiple pages but its header row does not repeat.

How to fix

Wrap the table header row in <thead> or add thead { display: table-header-group; } to your stylesheet. The renderer will then repeat the thead content on every page the table spans.

thead { display: table-header-group; }

Example

Before:

<table>
  <tr><th>Column</th></tr>
  <tr><td>Data</td></tr>
</table>

After:

<table>
  <thead>
    <tr><th>Column</th></tr>
  </thead>
  <tbody>
    <tr><td>Data</td></tr>
  </tbody>
</table>

In Markdown, use an HTML table block when you need explicit <thead> control, or ensure your Markdown table has a header row separated by --- dashes (GFM standard).
