Silverlight的Grid添加边框线【改编】

很多互联网上的资料，但是实际的开发效果差死了，防止一个组件，跑来跑去，烦。而且效果差，我改不出来，水平差。

不知哪位大虾修改一下，给我，我想一个简单实际的东西最好。研究那些东西也不赚钱；

关于边框线，真是麻烦，互联网上的改装都不能用，效果也差。真是不知道该说什么；

最后我综合意见，本着实战的原则，最后修改了一下；

不错吧，就这样了，实战关键，没有空研究。

各位有空再改装。不过打算使用ComponetOne,Radcontrols第三方组件啥的，就是ComponetOne提供了一个，结果难用的要死，写一大堆，而且灵活度差，因为FlexGrid不是可设计型容器，麻烦，不够实际。

今天开始优化了一下，对内部表格进行了布局处理。各位只要复制就可以使用；以下就是源代码，本人有代码洁癖，无论做什么事，都要
