* ActionColumn is a column for the [[GridView]] widget that displays buttons for viewing and manipulating the items.

|
|
* To add an ActionColumn to the gridview, add it to the [[GridView::columns|columns]] configuration as follows:
|
|
*
|
|
* ```php
|
|
* 'columns' => [
|
|
* // ...
|
|

* // you may configure additional properties here
|
|
* ],
|

|
|

|
|
* For more details and usage information on ActionColumn, see the [guide article on data widgets](guide:output-data-widgets).
