设计步骤简单说明
把TcxDBPivotGriD拖到窗口，设置DataSource,在TcxDBPivotGriD右击选择Designer,出现如下图
有几个字段就按几次ADD
选择FieldS下的cxDBPivotGrid1FieldX ，在对象 窗口设置好属性，常见的属性有
Area; Caption，FieldName,DataVisibility ;设置好后 单击CLOSE。即可
代码如下
object cxDBPivotGrid1: TcxDBPivotGrid
Left = 0
Top = 0
Width = 762
Height = 488
Align = alClient
DataSource = DataSource1
Groups = <>
TabOrder = 0
ExplicitWidth = 754
ExplicitHeight = 460
object cxDBPivotGrid1Field1: TcxDBPivotGridField
Area = faRow
AreaIndex = 0
IsCaptionAssigned = True
Caption = #35838#31243
DataBinding.FieldName = 'Cname'
Visible = True
UniqueName = #35838#31243
end
object cxDBPivotGrid1Field2: TcxDBPivotGridField
Area = faRow
AreaIndex = 1
IsCaptionAssigned = True
Caption = #23398#29983
DataBinding.FieldName = 'Sname'
Visible = True
UniqueName = #23398#29983
end
object cxDBPivotGrid1Field3: TcxDBPivotGridField
Area = faData
AreaIndex = 0
IsCaptionAssigned = True
Caption = #25104#32489
DataBinding.FieldName = 'score'
DataVisibility = dvCrossAndTotalCells
Visible = True
UniqueName = #25104#32489
end
