参考：
http://www.foxtable.com/webhelp/topics/2334.htm，合并的时候先查一查是否有同代码的行，有就合并，没有就新增
Dim Book As New XLS.Book("c:\test\订单.xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("订单").StopRedraw()
Dim nms() As String = {"物料代码","数量","列1","列2","……"}
For n As Integer = 1 To Sheet.Rows.Count -1
Dim bh As String = sheet(n,0).Text
Dim dr As DataRow = DataTables("订单").Find("物料代码 = '" & bh & "'")
If dr Is Nothing Then '如果不存在同编号的订单
dr = DataTables("订单").AddNew()
For m As Integer = 0 To nms.Length - 1
dr(nms(m)) = Sheet(n,m).Value
Next
else ‘如果存在就合并数量
dr("数量") = dr("数量")+Sheet(n,1).Value
End If
Next
Tables("订单").ResumeRedraw()
