GridView Widget

The GridView widget takes data from a data provider and presents data in the form of a table. Each row of the table represents a single data item, and a column represents an attribute of the item.

Step 1 − Modify the datawidget view this way.

<?php
   use yii\grid\GridView;
   echo GridView::widget([
      'dataProvider' => $dataProvider,
   ]);
?>

Step 2 − Go to http://localhost:8080/index.php?r=site/data-widget, you will see a typical usage of the DataGrid widget.

The columns of the DataGrid widget are configured in terms of the yii\grid\Column class. It represents a model attribute and can be filtered and sorted.

Step 3 − To add a custom column to the grid, modify the datawidget view this way.

<?php
   yii\grid\GridView;
   echo GridView::widget([
      'dataProvider' => $dataProvider,
      'columns' => [
         'id',
         [
            'class' => 'yii\grid\DataColumn', // can be omitted, as it is the default
            'label' => 'Name and email',
            'value' => function ($data) {
               return $data->name . " writes from " . $data->email;
            },
         ],
      ],
   ]);
?>

Step 4 − If you go to the address http://localhost:8080/index.php?r=site/data-widget, you will see the output as shown in the following image.

Grid columns can be customized by using different column classes, like yii\grid\SerialColumn, yii\grid\ActionColumn, and yii\grid\CheckboxColumn.

Step 5 − Modify the datawidget view in the following way.

<?php
   use yii\grid\GridView;
   echo GridView::widget([
      'dataProvider' => $dataProvider,
      'columns' => [
         ['class' => 'yii\grid\SerialColumn'], 'name',
         ['class' => 'yii\grid\ActionColumn'],
         ['class' => 'yii\grid\CheckboxColumn'],
      ],
   ]);
?>

Step 6 −Go to http://localhost:8080/index.php?r=site/data-widget, you will see the following.
