PS：请自行忽略gif的水印，使用Function REUSE_ALV_FIELDCATALOG_MERGE后注意单行代码不要超过72字节
ALV的复选框有两种方式实现，一种是使用Layout属性，另一种是使用Fieldcat属性
1、Layout实现方式（最简单的实现方式，这种方式能直接使用ALV报表自带的全选和反全选按钮，多选的话需要按住Ctrl再进行鼠标点选）

运行效果：
2、Fieldcat实现方式（设置edit属性的时，会多出Layout方式的选择框效果，此复选框在此处无任何作用，未设置edit属性时，复选框在Fiori页面上又显示灰色，感觉不友好；不过Fieldcat实现方式不可使用ALV报表自带的全选和反全选按钮，需要自定义全选和反全选的点击按钮事件）
