我有个窗口 里面有导入excel文件按钮 点击按钮 打开对话框导入excel文件 代码如下：
Dim TableName As String = "当天配送会员窗口_Table1"
Dim dlg As New OpenFileDialog '定义一个新的OpenFileDialog
dlg.Filter = "Excel文件|*.xls|Word文件|*.doc|Access文件|*.mdb"
If dlg.ShowDialog = DialogResult.OK Then '如果用户单击了确定按钮
Dim Book As New XLS.Book(dlg.FileName)
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables(TableName).StopRedraw()
Dim dtb As New DataTableBuilder("统计")
For n1 As Integer = 0 To Sheet.Cols.Count - 1
dtb.AddDef(Sheet(0, n1).Text, Gettype(String), 32)
Next
Tables(TableName).DataSource = dtb.BuildDataSource
For n As Integer = 1 To Sheet.Rows.Count - 1
Dim bh As String = Sheet(n, 0).Text
Dim dr As Row = Tables(TableName).AddNew()
For m As Integer = 0 To Tables(TableName).Cols.Count - 1
dr(Tables(TableName).Cols(m)) = Sheet(n, m).Value
Next
Next
End If
Tables(TableName).ResumeRedraw()
但是这个会把我之前的Table里面的数据清空掉 我是想导入excel 数据是追加在原来数据后面的 怎么实现？？
