> 值`string`如：`id`
> 值`array`配置联合主键如：`['role_id, 'auth_id']`
示例代码：

return ViewBuilder::table()
->setPage(true)
->setHideCheckbox(false)
->setColumns([
'password',
'username' => table_column_helper('用户名', ['style' => ['min-width' => '100px']]),
'an_mobile' => table_column_helper('电话', ['style' => ['min-width' => '100px']], function($item){
return '+' . $item['an'] . ' ' . $item['mobile'];
}),
'email' => table_column_helper('邮箱', ['style' => ['min-width' => '200px']]),
])
->setQuery(function () {
$query = AdminUser::find()->select(['id', 'username', 'password', 'email', 'an', 'mobile']);
return $query;
})
->setOrderBy('id DESC')
->setPrimaryKey('id')
->render($this);
