主题：[求助]可视化授权，对窗口中RecordGrid1绑定表，只能实现“禁止编辑”，而不能实现“对指定列不可见”？

For Each t As Table In Tables
    t.Visible = True
    t.AllowEdit = true
    For Each c As Col In t.Cols
        c.Visible = True
        c.AllowEdit = True
    Next
Next
Tables("授权表").Visible = (User.Type <> UserTypeEnum.User )
If User.Type = UserTypeEnum.User Then
    For Each dr As DataRow In DataTables("授权表").Select("用户名 = '" & User.Name & "'" )
        If dr.IsNull("列名") Then
            Tables(dr("表名")).Visible = Not dr("不可见")
            Tables(dr("表名")).AllowEdit = Not dr("不可编辑")
        Else
            Tables(dr("表名")).Cols(dr("列名")).Visible = Not dr("不可见")
            Tables(dr("表名")).Cols(dr("列名")).AllowEdit = Not dr("不可编辑")
        End If
    Next
End If

怎样才能做到，可以对具体窗口控件绑定表的制定列进行授权？
