Question

我有下表，我正试图将th的文字居中。

<table id="tblProgressSUmmary" class="table table-hover table-striped table-bordered table-condensed responsive dataTable no-footer dtr-inline collapsed" role="grid" aria-describedby="tblProgressSUmmary_info" style="width: 2082px;">
    <thead>
        <tr role="row">
        <th class="sorting_asc" tabindex="0" aria-controls="tblProgressSUmmary" rowspan="1" colspan="1" style="width: 52px;" aria-sort="ascending" aria-label="Running Track: activate to sort column descending">Running Track</th>
        <th class="sorting" tabindex="0" aria-controls="tblProgressSUmmary" rowspan="1" colspan="1" style="width: 66px;" aria-label="Exc Type: activate to sort column ascending">Exc Type</th><th class="sorting" tabindex="0" aria-controls="tblProgressSUmmary" rowspan="1" colspan="1" style="width: 88px;" aria-label="Progress Quantity: activate to sort column ascending">Progress Quantity</th>
        <th class="sorting" tabindex="0" aria-controls="tblProgressSUmmary" rowspan="1" colspan="1" style="width: 88px;" aria-label="Avg Duration: activate to sort column ascending">Avg Duration</th>
        </tr>
    </thead>
    <tbody>
        <tr class="odd">
        <td valign="top" colspan="10" class="dataTables_empty">No data available in table</td>
        </tr>
    </tbody>
</table>

和css：

#tblCIPSUmmary  > thead {
    font-size:11px;
    letter-spacing:1px;
    margin:auto;
}

tr {
    margin:auto;
}

Answer 2

只需在代码中添加以下Css

thead tr th { 文本对齐：中心; }

Answer 3

Bootstrap有一个预定义的类名，用于居中对齐文本，您可以使用“ text-center ”类，以便您的元素与中心对齐。

.text-center{text-align:center;}

使用margin auto将文本对齐到中心不适用
