如何在Yi2 gridview中一行显示大数据表的表头名称

我在gridview中有一个表，它有很多列。现在，我增加了列宽以调整标题名称，但没有用。标题仍显示在两行中，我使用了以下方法：

'contentOptions' =>['style' => 'width:30px'], 

调整列宽。有没有办法增加整个gridview的宽度，这样我就可以增加列宽并使标题显示在一行中？ 以下是我的gridview代码：

<div class="listing-width">
                <?php Pjax::begin(); ?>

                    //       / 'filterModel' => $searchModel,
                    'layout' => "\n{items}\n<div class='row'><div class='text-xs-left col-md-6'>{summary}</div><div class='text-xs-right col-md-6'>{pager}</div></div>",

                  </div> 

在css文件中：

.grid-view {
    width: ...px !important;
    overflow-x: scroll !important;
}

找到解决方案：

您必须围绕“Gridview”创建一个div，并将类分配给该div，例如：class=listing width

在该div上应用以下css：

.listing-width {
   overflow-x: scroll;
}
.listing-width  table{
   max-width: ....px;
    width: ....px;
}

然后为每列的标题指定宽度：

'headerOptions' => [ 'style'=>'width: ....px']

这将解决一行中包含大量列且带有“标题”和水平滚动条的表的问题。
请尝试以下操作：-）
网格中

[或]在CSS中

.grid-view th {
    white-space: nowrap;
}

我也尝试过为每一列设置宽度，但它没有帮助，因为我有大量的列。有没有办法增加整个gridview的宽度并在其上添加滚动条？如果我能够增加gridview的宽度，然后为每一列应用宽度，那么它可能会解决我的问题，但我不知道如何增加gridview宽度？是否要根据标题行内容设置标题行的宽度？
.grid-view th {
    white-space: nowrap;
}
