    <thead>
        <tr>
            <th class="table-info">NIP</th>
            <th class="table-info">Nama</th>
            <th class="table-info">Hak Akses</th>
            <th class="table-info">Kelas Mengajar</th>
        </tr>
    </thead>
    <tbody>
        <?php
            $show = mysqli_query($conn, "SELECT * FROM user");
            while ($row = mysqli_fetch_assoc($show)) {
                echo "<tr>
                        <td>$row[nip]</td>
                        <td>$row[nama]</td>
                        <td>$row[role]</td>
                        <td>$row[kelas]</td>
                    </tr>
                ";
            }
        ?>
    </tbody>
</table>

I want the result window.print() the function is the same as the page I created that contains a table with bootstrap styles.
