 In this article, we will show you how to manage cell editing and submission When enabling checkbox column in [Flutter DataTable](https://www.syncfusion.com/flutter-widgets/flutter-datagrid).
 
-Initialize the [SfDataGrid](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/SfDataGrid-class.html) widget with all required properties. To enable the checkbox column, set the [showCheckboxColumn](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/SfDataGrid/showCheckboxColumn.html) property to true at the sample level. In SfDataGrid, the checkbox column is always added as the first column. To resolve the column index on [onCellSubmit](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/DataGridSource/onCellSubmit.html) at the sample level, check if the showCheckboxColumn is enabled. This ensures that you can perform editing and submit the new cell value to the correct cell on the [DataGridRow](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/DataGridRow-class.html).
