Well in my example I create a new DataGridColumn object to add to the
DataGrid. So all the properties available to any DataGridColumn
(headertext, width, resizable, etc) can be set directly on the new
DataGridColumn object once it has been created.
var col:Object = new DataGridColumn("bool");
col.width=150;
col.headerText = "foo";
dg.addColumnAt(0, col);

Thanks guys. All your points were very helpful
One more thing. If I use Deepa's solution how do I change the
attributes of the column e.g headertext, width
