接續之前"將視窗拆成2*3的窗格"，要在上面多一行Menu沒想到有點複雜，設定上有些眉角，一點小錯就可能讓排版走位
關鍵在把視窗切割成2*4，再把上面2格合併，配置給Menu
| Menu (Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2") |
| AA (Grid.Row="1" Grid.Column="0") | AB (Grid.Row="1" Grid.Column="1") |
| BA (Grid.Row="2" Grid.Column="0") | BB (Grid.Row="2" Grid.Column="1") |
| CA (Grid.Row="3" Grid.Column="0") | CB (Grid.Row="3" Grid.Column="1") |

MenuItem的設計和程式的結束事件(MenuItemExit_Click)也有需要小心的地方，這部分之後補充
