BeforeLoadOuterTable(外部表)中设置代码：

Select Case e.DataTableName
    Case "表A","表B" '表A和表B无条件加载
    Case "表C"
        If e.User.Type <> UserTypeEnum.Developer Then '只有开发者才加载表C
            e.Cancel = True
        End If
    Case Else '其他所有表默认都不加载
        e.Cancel = True
End Select

初始不加载表，是不是在打开窗口的afterload用 datatables（"A"）来引用加载？

主题：登录按钮的代码是这些，现在加载还是很慢，从点登陆到主窗口要15秒，我已经将部分表限制加载了还是一样。
