Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls;*.xlsx"
If dlg.ShowDialog =DialogResult.OK Then
Dim t As Table = Tables("海报印刷与投递费用")
Dim cs As String() = {"门店名", "订单号", "印刷量","投递量"}
Dim cs2 As String() = {3,4,7,8}
t.StopRedraw()
Dim Book As New XLS.Book(dlg.FileName) '定义一个Excel工作簿
Dim Sheet As XLS.Sheet = Book.Sheets(0) '引用工作簿的第一个工作表
For n As Integer = 2 To Sheet.Rows.Count -1
Dim r As DataRow = t.DataTable.Find("门店名 = '" & sheet(n, 3).text & "'")
If r Is Nothing Then r = t.DataTable.AddNew()
For i As Integer = 0 To cs2.length-1
r(cs(i)) = sheet(n, cs2(i)).Text
Next
Next
t.ResumeRedraw()
End If
以上代码可以导入，但是为什么导入每个表都会把原来的覆盖？不知道哪出错了？
