html - 如何在表格中对齐标题？

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>

解决方案

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( {
    language: { "search": "Filter"},
    paging: false,
    info: true,
    scrollY:'50px',
    scrollCollapse: true,
    scrollX: false,
   });
});
/*table {
    width: 100%;
    table-layout: fixed;
}*/

th {
    font-size: 15px;
    font-weight: bolder;
    text-align: center;
}

td {
    font-size: 15px;
    text-align: center;
}

table.table-bordered {
    border: 2px solid black;
}

table.table-bordered > thead > tr > th {
    border: 1px solid black;
    background-color: lightgrey;
}

table.table-bordered > tbody > tr > td{
    border: 1px solid black;
    border-top: 1px solid;
}

/*thead {
    display: table;
    width: 100%;
}

tbody {
    display: block;
    height: 200px;
}*/
