php - 如何在 table 上放一个粘头

Question

我希望 thead 在表格中滚动时不移动，我无法在 tbody 上设置自动溢出，所以我该如何解决？

我已经尝试过 style="overflow: auto; height: 650px;"在 tbody 上，但它根本不起作用

<div class="row m-t-30">
    <div style="overflow: auto; height: 650px;" class="col-md-12">
        <div class="table-responsive m-b-40">
            <table id="productsTable" class="table table-borderless table-data3">
                <thead>
                <tr>
                    <th>Klant</th>
                    <th>Werknemer</th>
                    <th>Datum</th>
                    <th></th>
                </tr>
                </thead>
                <tbody>
                <?php
                foreach ($clients->getAllclients() as $client) {
                    echo '<tr>';
                    echo '<td>' . $client['client_name'] . '</td>';
                    echo '<td>' . $client['client_id'] . '</td>';
                    echo '<td>' . $client['client_address'] . '</td>';
                    echo '<td><button class="item" data-toggle="tooltip" data-placement="top" title="See" onclick="seeOrder(\'' . $client['client_id'] . '\')"><i style="font-size: 20px" class="zmdi zmdi-search"></i></button></td>';
                    echo '</tr>';
                }
                ?>
                </tbody>
            </table>
        </div>
    </div>
</div>

您可以使用 position: sticky; 表格

table thead tr th {
  background-color: white;
  position: sticky;
  top: -1px;
}

下面是粘性广告的演示

table thead tr th {
  background-color: white;
  position: sticky;
  top: -1px;
}
