InDesign CC2019+2020
Create a table
Convert first row to Header row type
Convert last row to Footer row type
Export to HTML
you get (simplified)
<table>
    <thead>
        <td>
              <p>Text</p>
        </td>
    </thead>
    <tfoot>
        <td>
              <p>Text</p>
        </td>
    </foot>
    <tbody>
        <td>
              <p>Text</p>
        </td>
    </tbody>
The HTML spec specifies that tfoot should appear AFTER tbody.
Also the <td> in <thead> should be <th>.
