title: Yii2: GridView's column is too wide
body: <p>I have <code>index.php</code> made by the <strong>Gii</strong> tool that created a CRUD. Also I use <strong>AdminLTE</strong> template.</p>
  
  <p>It has the <strong>GridView</strong> that should show two columns: "Phrase" and "Author" but the column "Phrase" has some rows with long text (around 350 characters) so just <strong>a part of this column is shown</strong>. And the "Author" column is not shown at all.</p>
  
  <p>There is no <strong>horizontal scroll bar</strong> (it should help me):</p>

  <p>Or maybe the problem is the <strong>string</strong> data type:</p>
  
  <pre><code>public function rules()
  {
      return [
          [['phrase'], 'required'],
          [['phrase'], 'string'],
          [['author'], 'string', 'max' =&gt; 50],
      ];
  }
  </code></pre>
  
  <p>This is my <code>index.php</code> view:</p>
  
  <pre><code>&lt;div class="box box-primary"&gt;
      &lt;?php Pjax::begin(); ?&gt;                
      &lt;?= GridView::widget([
          'dataProvider' =&gt; $dataProvider,
          'filterModel' =&gt; $searchModel,
          'columns' =&gt; [
              'phrase',
              'author',
          ],
      ]); ?&gt;
      &lt;?php Pjax::end(); ?&gt;
  &lt;/div&gt;
  </code></pre>
