Yii2 GridView是实现yii网格视图的小部件，一般用于报表视图的展示。今天，结合DataProvider（ArrayDataProvider以及SqlDataProvider）说一下GridView中的几个Columns(SerialColumn,DataColumn,ActionColumn)。
1. SerialColumn
SerialColumn就是连续的列，主要用于网格的行号，属于自增式的列。用法很简单：
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'], // 连续编号
// 其他数据列和操作列
]
]);展示结果：
| # |
| 1 |
| 2 |
2. DataColumn
DataColumn主要展示数据的，所有跟数据有关的展示基本都在这个Column中实现。因此用法也很多，但是有一条，如果对数据不做处理，那么字段必须是ArrayDataProvider对象的allModels的二维数组的key或者是SqlDataProvider对象sql查询结果二维数组的key。
用法一：表头即字段名，首字母大写
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
'orderNo', //订单编号
'username' // 用户名
]
]);展示结果：
| OrderNo | Username |
| 123345698763 | Test用户 |
| 236479547829 | Joyven |
用法二：定义表头并格式化数据
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
'time:date:日期',
'pv:raw:PV',
'uv:raw:UV',
]
]);展示结果：
| 日期 | PV | UV |
| 2016年9月10日 | 8500 | 6384 |
| 2016年9月9日 | 8378 | 6523 |
用法三：数据过滤，class、attribute、label、format均不是必须要的。class默认是yii\grid\DataColumn，attribute是指定排序的字段key，一定是dataProvider中提供的数据的key，如果不指定，对于过滤的数据，不能点击表头排序。
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
[
'value' => function($data) {
if (isset($data['time'])) {
return date('Y-m-d', $data['time']);
}
},
'attribute' => 'time', //用于排序，如果不写，不能点击表头排序，非必须
'label' => '日期', // 自定义表头，非必须
'format' => 'raw', // 格式方式，非必须
],
'pv:raw:PV',
[
'class' => 'yii\grid\DataColumn',
'value' => function ($data) {
if (isset($data['orderCr'])) {
return ($data['orderCr'] * 100) . '%';
}
},
'attribute' => 'orderCr',
'label' => '下单转化率',
'format' => 'raw',
],
]
]);关于format支持的格式：
| format | 说明 | 参数 | 返回 | 备注 | |

3. ActionColumn
ActionColumn是对一行数据进行操作的句柄。class指定处理的类，必须。 header指定表头显示，如果不写，默认为空。非必须。 template中默认有三个：{view} {update} {delete}，如果需要其他的，自行添加，比如下面添加了{onshelf} {offshelf} {robot}这三个。buttons除了默认的三个可以不写，其他都必须写。
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
[
'class' => 'yii\grid\ActionColumn',
'header' => '操作’,
'template' => '{view} {update} {delete} {onshelf} {offshelf} {robot}',
'buttons' => [
'onshelf' => function ($url, $model, $key){
return $model['status'] ? '' : Html::a('',
['item/shelf'],
['title' => '上架商品', 'data' => ['method' => 'post', 'id' => $key, 'type' => 'on'], 'class'=> 'shelf']);
},
'offshelf' => function ($url, $model, $key){
return $model['status'] ? Html::a('',
['item/shelf'],
['title' => '下架商品', 'data' => ['method' => 'post', 'id' => $key, 'type' => 'off'], 'class'=> 'shelf']) : '';
},
'robot' => function ($url, $model, $key){
return Html::a('',
['robot/like', 'id' => $model['pid'] ],
['title' => '自动点赞', 'class' => 'post-autolike', 'data' => ['method' => 'post']]) ;
},
]
],
],
]);
