问题 I've been able to drag a PivotTable out onto the dance floor, but haven't been able to get it to boogie down - it seems we keep stepping on each other's toes. I've got data already on the sheet from which to build the Pivot Table. This class describes that data: public class PriceVarianceData { public String Unit { get; set; } public String ShortName { get; set; } public String ItemCode { get; set; } public String Description { get; set; } public String PriceWeek { get; set; } public String
