I had a very similar issue with the Flowbite library. What solved it was adding the <tr> element:

<div className="overflow-x-auto">
  <Table striped>
    <TableHead>
      <tr> {/* ~~~ ADD THIS <TR> ~~~ */}
        <TableHeadCell>xxx</TableHeadCell>
        ...
      </tr>
    </TableHead>
  </Table>
</div>
