The string can contain parameters that represent information about their corresponding group:
{0} represents the title or field name of the column by whose values the items are grouped. By default, the column's Title will be used (e.g., "Country"); however, if the UseFieldNamesInHeader property is set to true, the column's FieldName will be used (e.g., "ShipCountry").
{1} represents the value of the group (e.g., "Canada").
{2} represents the number of items in the group.
{3} represents a value indicating whether the group has child groups.
If set to null, group headers will not be displayed.
