导入还是导出?
类似
Dim dt As Table = Tables("表A")
Dim Book As New XLS.Book("F:\111.xls") '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
Dim len As Integer = sheet.Rows.Count
For r As Integer = 0 To dt.Rows.Count - 1 '填入数据
For c As Integer = 0 To dt.Cols.Count -1
Sheet(len + r, c).Value = dt.rows(r)(c)
Next
Next
'打开工作簿
Book.Save("F:\111.xls")
Dim Proc As New Process
Proc.File = "F:\111.xls"
Proc.Start()
