# Row Action Command
## Content
TableSheet provides row action commands that can be implemented when clicking on row headers to perform certain action using the **command** property.
SpreadJS also provides a few built-in row action options that can be implemented on row headers.
| **Name** | **Description** |
| ------ | ------------- |
| dirtyStatus | Show the data change in a row |
| pinRow | Pin a row |
| removeRow | Remove a row |
| resetRow | Reset the data change in a row |
| saveRow | Save the data change in a row |
| warningInfo | Show warning information in a row |
The following code sample shows how the **PinRow** command is used to pin the selected row headers.
```javascript
var options = sheetTab.rowActionOptions();
var defaultRowAction = options[0];
defaultRowAction.command = 'PinRow'; // built-in pin row command
```
