SSRS/SQL将数据分组为PB报告中的数据

我们正在将PB迁移到SSRS报告，在一个报告中，他们希望将报告显示为以下格式。基本上，在检索时按日期列排序，然后按客户名称应用组，如下所示

我正试图通过SSR或使用SQL在SSR中实现同样的目标

        Sample script. 

        Create table #Sample (CustomerName varchar(10),InvDate datetime, Invamount INT)

        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('Rocky','1/2/2001',100)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('Vicky','1/1/2002',200)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('Rocky','1/1/2003',300)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('Vicky','1/1/2000',400)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('SMART','1/1/2001',600)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('Rocky','1/1/2005',700)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('Rocky','1/1/2006',800)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('SMART','1/1/2001',900)
        Insert into #Sample (CustomerName,InvDate,Invamount) Values ('SMART','1/1/2010',900)

        SELECT * from #Sample
        ORDER BY InvDate
