[求助]导入excel数据求助 - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

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)

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

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？？

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()
    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()

这样的话,你窗口的表列名什么的要和Excel表格的对应
