Your problem is that you don't have a "label" field or a "value" field on your model. So you are not printing anything because this fields don't exist. Try something like this:

    {% for field in clientes %}
        <td>{{ field.madotxep |default_if_none:'' }}</td>
        <td>{{ field.hodem |default_if_none:'' }}</td>
        <td>{{ field.ten |default_if_none:'' }}</td>
        <td>{{ field.viettat |default_if_none:'' }}</td>
    {% endfor %}

django template itself don't render the table for you with label or value, you need to specify the table header and it's contents in the loop yourself:

<table>
    <thead>
        <th>id</th>
        <th>madotxep</th>
        <th>hodem</th>
        <th>ten</th>
        <th>viettat</th>
        <th>nhomgv</th>
        <th>mamau</th>
        <th>stt</th>
        <th>ghichu</th>
    </thead>
    <tbody>
        {% for client in clientes %}
        <tr>
            <td>{{ client.id|default_if_none:'' }}</td>
            <td>{{ client.madotxep|default_if_none:'' }}</td>
            <td>{{ client.hodem|default_if_none:'' }}</td>
            <td>{{ client.ten|default_if_none:'' }}</td>
            <td>{{ client.viettat|default_if_none:'' }}</td>
            <td>{{ client.nhomgv|default_if_none:'' }}</td>
            <td>{{ client.mamau|default_if_none:'' }}</td>
            <td>{{ client.stt|default_if_none:'' }}</td>
            <td>{{ client.ghichu|default_if_none:'' }}</td>
         </tr>
        {% endfor %}
    </tbody>
