--  [求助]先判断每个单元格都有数据才合并导入

在帮助文档中有数据合并导入的代码如下，如果我想先判断要导入的订单表（订单.xls）是不是每一列的每个单元格都有数据，如果数据没有空则导入，如果数据有空则提醒“数据有空白”

请问各位大神，怎么实现呢？


Dim Book As New XLS.Book("c:\\test\\订单.xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("订单").StopRedraw()
\'注意以下数组中列名称的顺序,必须和Excel表中的列顺序一致
Dim nms() As String = {"编号","产品","客户","雇员","单价","折扣","数量","日期"}
\'注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题
For n As Integer = 1 To Sheet.Rows.Count -1
    Dim bh As String = sheet(n,0).Text
    If DataTables("订单").Find("编号 = \'" & bh & "\'") Is Nothing Then \'如果不存在同编号的订单
        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()

先判断，如

Dim Book As New XLS.Book("c:\\test\\订单.xls") 
Dim Sheet As XLS.Sheet = Book.Sheets(0)
\'注意以下数组中列名称的顺序,必须和Excel表中的列顺序一致
Dim nms() As String = {"编号","产品","客户","雇员","单价","折扣","数量","日期"} 
\'注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题 
For n As Integer = 1 To Sheet.Rows.Count -1 
   For m As Integer = 0 To nms.Length - 1
   If Sheet(n,m).text = ""
msgbox("数据有空白,行" & n & ",列" & m)
Return
End If
   Next
Next
Tables("订单").StopRedraw()
\'注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题 
For n As Integer = 1 To Sheet.Rows.Count -1 
    Dim bh As String = sheet(n,0).Text 
    If DataTables("订单").Find("编号 = \'" & bh & "\'") Is Nothing Then \'如果不存在同编号的订单
        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()
