经常会有需求让在标准的order加个assign block，那就来简单说一下：
1.创建assign block组件ZXXXXXX
2.添加BTORDER节点和GUID属性
3.创建表视图（可配置，根据情况是否按钮），在表的初始化中DO_INIT_CONTEXT或者DO_PREPARE_OUTPUT中根据GUID带出block信息

将组件添加InterfaceView 并把BTorder节点添加。
将组件添加到BT116H_SRVO的ComponentUsage
在BT116H_SRVO的组件控制器的WD_USAGE_INITIALIZE的方法中添加GUID节点的映射：

在OverView Page中将组件视图添加进来，然后在配置中将组件放出，即可显示。
