我们可以通过类CL_SALV_DISPLAY_SETTINGS中的一些方法进行SALV显示的设置，本教程演示如何设定Zerbra style和设定SALV的title，方法如下：
1，调用get_display_settings取得CL_SALV_DISPLAY_SETTINGS的引用
2，调用类CL_SALV_DISPLAY_SETTINGS中的方法set_striped_pattern()和set_list_header()
当然CL_SALV_DISPLAY_SETTINGS中还有很多其他的方法，具体可以通过SE24查看，如下：
在之前SALV教程2-添加标准状态栏(status)代码的基础上添加方法set_display_setting()，UML流程图如下：
完整代码如下：
