如何实现DataTables固定标头功能？

时间：2019-03-19 16:48:35

标签： html css datatables

我正在使用DataTables插件，并且希望我的表具有固定的标题。过去也曾发布过类似的其他问题，但是即使有这些问题，我仍然无法使它起作用。我不确定是什么问题...也许我在竞争CSS或缺少CDN（我不知道）。

在此，我将不胜感激。谢谢

$(document).ready(function () {
        $('#dtBasicExample').DataTable({

答案 0 :(得分：2)

我看到有几个代码问题。

1）您需要添加以下脚本标签<script src="https://cdn.datatables.net/fixedheader/3.1.5/js/dataTables.fixedHeader.min.js"></script>

2）您需要添加以下CSS <link rel="stylesheet" href="https://cdn.datatables.net/fixedheader/3.1.5/css/fixedHeader.dataTables.min.css">

3）您有一些重复的<script>标签，例如jquery被多次添加，页面底部也有一些标签。

4）建议jQuery应该是第一个<script>标记。

最后，这是小提琴中的工作副本：https://jsfiddle.net/zwuq20cp/
