i using yii2 gridview widget showing data in form of table.

as there many fields show, gridview ( below table ) showing scroll it. don't want it.

i want increase container width show table without scroll.

i had search bootstrap.css file not found in directory.

how change gridview width ? 

 <?= gridview::widget([         'dataprovider' => $dataprovider,         'filtermodel' => $searchmodel,         'columns' => [             ['class' => 'yii\grid\serialcolumn'],       .........             ['class' => 'yii\grid\actioncolumn'],         ],     'tableoptions' =>['style' => 'width: 1800px;'],     ]); ?>

or gridview container options

 <?= gridview::widget([         'dataprovider' => $dataprovider,         'filtermodel' => $searchmodel,         'columns' => [             ['class' => 'yii\grid\serialcolumn'],       .........             ['class' => 'yii\grid\actioncolumn'],         ],     'options' =>['style' => 'width: 1800px;'],     ]); ?>

otherwise if need larger page container need new layout

add tye new layout in app/views/layout eg:changing container this way 

    ....     <div class="container-fluid">         <?= breadcrumbs::widget([         'links' => isset($this->params['breadcrumbs']) ? $this->params['breadcrumbs'] : [],     ]) ?>     <?= alert::widget() ?>     <?= $content ?>     </div>     ....

then assign new layout view before render 

    public function actionindex()     {           ......          $this->layout = 'my_new_layout'         return $this->render('index', [             'searchmodel' => $searchmodel,             'dataprovider' => $dataprovider,         ]);     }
