This example contains 6 layouts of different kinds: 
 Simple Layout: a basic layout but which includes a Calculated Column (Avg Item Cost) and a FreeText Column (Comments) 
 Col Widths Layout: a layout where 2 columns (OrderId and Comments) are given wider initial widths.
 Sorting Layout: a layout which contains 2 sorted columns (ShipName and ShipVia), the latter of which also has a Custom Sort.
 Grouping Layout: which groups on the Employee and Ship Country columns
 Pivoting Layout which defines the following pivoting definition:
Pivot on the ShipVia column (the PivotColumns property) - note that we automatically uses the Custom Sort defined for that this column.
Group on the Employee column (the RowGroupedColumns property)
Show aggregation totals for the InvoicedCost (sum) and ItemCost (avg) columns (the AggregationColumns property)
 Advanced Layout: bit of everything
