In your .fla file make sure you have the imports:

import fl.controls.DataGrid;
import fl.controls.dataGridClasses.DataGridColumn;
import fl.controls.listClasses.CellRenderer;
import ButtonCell;

Then, in your .fla file use this to create the column (where 'myDataGrid' is the name of your dataGrid instance):

var btnCol:DataGridColumn = new DataGridColumn("buttonColumnTitle");
btnCol.cellRenderer = ButtonCell;
btnCol.editable = false;
myDataGrid.addColumn(btnCol);
                 

To set the button label, just set the text like you would any other dataGrid cell:

myDataGrid.addItem({buttonColumnTitle:"Button Label"})
