Question

Firefox中没有显示表格边框。如果 tfoot 内的 tfoot 或 tr 被删除，则显示边框。

<div class="container">
<div class="table-responsive">
    <table class="table table-bordered table-striped">
        <thead>
            <tr>
                <th>Name</th>
                <th>Email</th>
            </tr>
        </thead>
        <tfoot>
            <tr>
                <td>Total 1 person</td>
                <td></td>
            </tr>
        </tfoot>
        <tbody>
            <tr id="test">
                <td>Mohammed</td>
                <td>mytestmail@gmail.com</td>
            </tr>
        </tbody>
    </table>
</div>
