前言：
当前朋友们对“grid function”大约比较注意，小伙伴们都需要剖析一些“grid function”的相关文章。那么小编也在网络上收集了一些对于“grid function””的相关知识，希望咱们能喜欢，各位老铁们快快来了解一下吧！项目上有时候遇到特殊需求要在同一个屏幕上显示多个ALV，比如一个ALV显示抬头数据，另一个ALV显示明细数据。对于这样的要求可以通过以下的方法来实现，主要用到的相关类：CL_GUI_SPLITTER_CONTAINER
其中实现的关键代码：设置分割容器。
最终实现效果如下：
刚开始运行程序后，第一个ALV显示数据，第二个ALV没有显示数据；双击第一个ALV中的某一行，则第二个ALV显示相应的数据。
具体实现的全部代码如下：
