主题：“角色”参与授权管理

如何修改以下代码可以让“分组”和“角色”都参与授权管理：

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("分组名 = '" & User.Group & "'" )
        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
