是否添加wpf ListView组？

我已经创建了

listview

，并通过

vb.net

code添加了列

这是我的密码：

XMAL代码

 <ListView Grid.Row="1" Name="LV1" />

    'Create Grid View & Add Columns to Grid View 
    Dim GV1 As New GridView
    GV1.Columns.Add(New GridViewColumn With {.Header = "Inv. No.", .Width = 100, .DisplayMemberBinding = New Binding("No2")})
    GV1.Columns.Add(New GridViewColumn With {.Header = "Party", .Width = 200, .DisplayMemberBinding = New Binding("GLDisplay")})
    GV1.Columns.Add(New GridViewColumn With {.Header = "Broker", .Width = 100, .DisplayMemberBinding = New Binding("Br")})
    GV1.Columns.Add(New GridViewColumn With {.Header = "Inv. Value", .Width = 100, .DisplayMemberBinding = New Binding("Total")})
    GV1.Columns.Add(New GridViewColumn With {.Header = "Outstanding", .Width = 100, .DisplayMemberBinding = New Binding("Os")})

    'Set Date Formatting on Required Columns
    GV1.Columns(3).DisplayMemberBinding.StringFormat = "#0.00"
    GV1.Columns(4).DisplayMemberBinding.StringFormat = "#0.00"

    LV1.View = GV1 : LV1.ItemsSource = DT1.DefaultView

现在我想将组添加到此

listview

类似这样的内容（仅分组部分）
