--  导入数据
老师您好，我想问一下导入数据，这是我的代码，我新增一条他就出很多的空值应该怎么修改呢
Dim dlg As New SaveFileDialog \'定义一个新的SaveFileDialog
dlg.Filter= "Excel文件|*.xls" \'设置筛选器
If dlg.ShowDialog = DialogResult.Ok Then
Dim Book As New XLS.Book(dlg.FileName)
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("t1").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 = {"姓名","学号","专业","学校","实习单位"}
\'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("t1").Find("学号 = \'" & bh & "\'") Is Nothing Then \'如果不存在同编号的订单
Dim r As Row = Tables("t1").AddNew()
For m As Integer = 0 To nms.Length - 1
r(nms(m)) = Sheet(n,m).Value
Next
End If
Next
Tables("t1").ResumeRedraw()
End If

3楼链接里有，使用字典把对应关系存下来。如果看不懂，就上传实例
