我试图在我的 html 页面中复制两个表，但在这两种情况下，表头相对于整个 html 页面保持固定，而不是仅相对于关联的归属表保持固定。我该如何解决这个问题？
如果可能的话，我想继续只使用 html 代码......

@Vaibs 发布正确的帖子，您可以输入 div ，然后输入您的代码。我的代码希望你能有所了解。

<div class="wrap">
    <table class="head">
        <tr>
            <td>Head 1</td>
            <td>Head 1</td>
            <td>Head 1</td>
        </tr>
    </table>
    <div class="inner_table">
        <table>
        <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
            <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
            <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
              <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
              <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
              <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
            <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
    </table>
    </div>
</div>

CSS

.wrap {
    width: 352px;
}

.wrap table {
    width: 300px;
    table-layout: fixed;
}

table tr td {
    padding: 5px;
    border: 1px solid #eee;
    width: 100px;
    word-wrap: break-word;
}

table.head tr td {
    background: #eee;
}

.inner_table {
    height: 100px;
    overflow-y: auto;
}

检查它演示
