1、功能介绍
在这节里，需要实现餐桌类型展示，类型点击切换事件，餐桌面板展示功能，细节很多，流程是UI设计布局-》后台业务逻辑-》视图模型绑定-》运行测试
2、UI设计布局
TabControl，StackPanel，Grid，ListBox都是常用的布局控件，用得很多，需要熟悉，象其他的TextBox，Image，Button等都是最基础的，这个模块布局是最复杂的，涉及到很多细节问题，同时属性绑定和命令绑定也是蛮多的，界面如下，这个界面看上去效果很不明显，不要紧，WPF的界面运行后就会呈现漂亮的。
具体代码如下，这就不一行一行的解释了

在这个布局会用到事件处理，模板，样式，触发器等，这些是WPF重要操作，invokecommandaction是命令绑定处理事件，command是绑定具体的动作，动作必须在视图模型viewmodel中有处理代码，commandparameter是命令参数，因为命令处理时要有根据参数的不同来响应不同的逻辑过程。
这里要特别注意一点就是listbox中每个选项的点击事件selectionchanged，对于同一个选项listitem来说，这个事件只会触发一次，再次点击同一个listitem时，该事件不会触发，这样就不符合需求，需要在后台进行巧妙的处理。
3、后台逻辑
4、视图模型
具体代码，注释很详细
