主题：excel报表合并模式问题

单时通过两种方法生成的报表一个是标准模式,一个却是自由合并.这是怎么回事呢?

1:   XLS.Reports("厂订单").Build()   '这个方法生成出来是标准合并,这符合我的原意

2:    Dim Book As New XLS.Book(ProjectPath & "Attachments\订单.xls") '打开模板

        Dim fl As String = ProjectPath & "Reports\订单.xls"

        Book.Build() '生成报表

        Book.Save(fl)     

        Dim App As New MSExcel.Application

        Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(fl)

        Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)

        Dim Rg As MSExcel.Range = Ws.Cells

        Rg.EntireRow.AutoFit  '自动调整行高

        App.Visible = True

求解答啊,,,,,,,
