在SALV教程1-创建简单SALV中介绍了通过SALV类如何创建一个简单的ALV，教程2中介绍如何基于类CL_SALV_TABLE添加一个标准PF Status.CL_SALV_TABLE中提供了方法 'get_functions'，'set_default'，通过这两个方法可以创建Status。
在之前的例子代码基础上，创建一个新的private method set_deault_status,
新的UML流程图如下：
完整代码如下：
METHOD set_pf_status. 部分，包括set_pf_status定义，实现以及调用部分，

程序运行结果，可以看到默认的status已经显示出来了。
以上。
