Enables column reordering in Shield UI Grid. When column reordering is enabled, grid columns can be dragged and dropped to have their position changed:

    dataSource: {
    columns: [
        { field: "ID", title: "Unique Number", format: "{0:c}" },
        { field: "name", title : "Name", width: "300px" }
    columnReorder: true

To see the setting in action, please refer to the Shield UI Grid Column Reorder demo.
