引导表选项卡中的数据表大小不正确 [英] Datatables improperly sized in bootstrap tab

问题描述

我有一个页面，该页面包含三个引导程序选项卡，每个选项卡中都有一个数据表.第一个选项卡中的数据表工作正常.但是，第二个选项卡中的数据表为半角，我不知道为什么.也没有应用CSS.

I have a page that has three bootstrap tabs and a datatable in each tab. The datatable in the first tab works fine. However, the datatable in the second tab is at half-width and I have no idea why. There's no css applied to it either.

这是第一个标签页的屏幕截图(工作正常)

Here's a screenshot of the first tab (works fine)

和第二个标签(数据表的半角宽度)

And the 2nd tab (datatable at half width)

我的代码:

$('#companies').DataTable({ //table in tab 1 (works fine)
        responsive: true
});


$('#companies2').DataTable({ //table in tab 2
        responsive: true
});

我的html:

<!-- tab start -->
<div class="container">
    <div class="row">
        <div class="col-md-12">
            <h1>Tabs</h1>
            <ul class="nav nav-tabs">
                <li class="active"><a href="#tab1" data-toggle="tab">Section 1</a></li>
                <li><a href="#tab2" data-toggle="tab">Section 2</a></li>
                <li><a href="#tab3" data-toggle="tab">Section 3</a></li>
            </ul>

            <!-- tab sections -->
            <div class="tab-content">
                <div class="tab-pane active" id="tab1">
                    <table id="companies" class="table table-striped table-bordered dt-responsive nowrap" cellspacing="0">

                <div class="tab-pane" id="tab3">
                    3rd
                </div>

            </div>

有人可以帮忙吗?

推荐答案

保留dataTable实例，即

Keep the dataTable instances, i.e.

var companies2 = $('#companies2').DataTable({
  responsive: true
})

然后使用 columns.adjust() 重新计算包含表格的标签页可见时的宽度:

Then use columns.adjust() to recalculate the widths when the tab holding the table becomes visible :

$('a[data-toggle="tab"]').on('shown.bs.tab', function(e) {
  if (e.target.hash == '#tab2') {
    companies2.columns.adjust().draw()
  }
})

完全未针对您的特定情况进行测试，但这当然是要走的路.

Completely untested with your specific scenario, but this is certainly the way to go.
