主题：返回绑定表实例

窗体加载过程执行如下代码：

Dim cmd As  new  SQLCommand()

cmd.CommandText = "Select * from [Page1$]"

cmd.C

dim srcxlstable as datatable =cmd.ExecuteReader()

Tables("窗口1_Table1").DataSource = srcxlstable

----------------------------------------------------------

在后期操作中若想返回srcxlstable表的实例，应该如何操作？
