ALV的相关函数：REUSE_ALV_GRID_DISPLAY 代表grid格式的alv，REUSE_ALV_LIST_DISPLAY，代表list格式的alv，
REUSE_ALV_FIELDCATALOG_MERGE：根据内表定义的数据字典对象快速生成fieldcat内表（必须要引用data element）。
此外还有一种以LVC结尾的ALV函数REUSE_ALV_GRID_DISPLAY_LVC，这个函数中的引用类型不再是slis，而是数据字典结构，而且与OO ALV所用到的类型也基本相同，所以推荐使用 LVC结尾的函数。
先介绍以下slis类型池的参数。
layout 主要用于ALV整体输出格式，结构属于类型池： type-pools:slis.
