主题：合并数据

傻孩子，这不很简单吗？ 判断一下单元格是不是空的即可：

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 = {"产品","客户","雇员","单价","折扣","数量","日期"}
For n As Integer = 1 To Sheet.Rows.Count -1
    If sheet(n,0)> "" AndAlso sheet(n,1) > "" AndAlso sheet(n,2) > "" Then
        Dim r As Row = Tables("订单").AddNew()
        For m As Integer = 0 To nms.Length - 1
            r(nms(m)) = Sheet(n,m).Value
        Next
    End If
Next
Tables("订单").ResumeRedraw()
