以excel格式下载动态数据表

Question

我有一个动态生成的数据表，其中包括标题。数据来自在后台运行的sql查询，并创建了一个模型和视图，并使用模型占位符在前面捕获了该模型和视图。我无法弄清楚如何为数据表添加“下载为CSV”。友善的帮助

    <!-- data -->
    <section id="data" class="mb-1 mt-5">
        <div class="container-fluid">
            <div class="row">
                <div class="col-md-12">
                <!-- <div id="wait" style="display:none">loader</div> -->
                    <div class="table-responsive">
                        <table class="table table-sm table-bordered bg-white" id="data">
                            <tbody>
                                <tr th:each="ftids:${ftids}">
                                    <th:block th:each="track:${ftids}">
                                        <td th:text="${track}"></td>
                                    </th:block>
                                </tr>
                            </tbody>
                        </table>
                    </div>

        return modelAndView;

}

每次生成数据表时我都会收到控制台错误。但是没有下载选项
