【中文标题】如何将 <th> 标题与表中的 <td> 对齐？【英文标题】：How to align <th> Header with <td> in Table? 【发布时间】：2020-11-30 10:16:55 【问题描述】：在 DataTable 中启用滚动条 (ScrollY) 后，无法将表头与表数据对齐。 我尝试了许多在线可用的解决方案，但它似乎不起作用。 我试过 display:block 但没有运气。

Datatable:
$(document).ready(function()
$("#TableName").Datatable(
language: "search": "Filter",
paging: false,
info: true,
scrollY:'200px',
scrollCollapse: true,
scrollX: false,
);
);
<table id="TableName" class="table table-hover table-bordered table-striped>
<thead style="display:block">
<tr>
<th>Item1</th>
<th>Item2</th>
<th>Item3</th>
<th>Item4</th>
</tr>
</thead>
<tbody>
% for item in items_json %
<tr>
<td> item.a </td>
<td> item.b </td>
<td> item.c </td>
<td> item.d </td>
</tr>
</tbody>
</table>
【问题讨论】：
您能分享用于创建数据表的部分代码吗？如果没有代码示例，很难弄清楚发生了什么。 嘿，我已经用代码更新了问题...如果您需要任何其他详细信息，请告诉我。 我认为您还需要添加 CSS，也许还需要添加屏幕截图或 jsfiddle jsfiddle.net/VM001/dzukjbh3 这里添加了jsfiddle。不知何故滚动条没有出现在这里，但它是我的网页 【参考方案1】：我必须删除你的一些 css 规则，但它似乎对我有用：
$(document).ready(function()
$("#P1SxTable").DataTable(

paging: false,

scrollCollapse: true,
scrollX: false,
);
