图标(ICON)和提示信息(tooltips)会使ALV更加易读，突出重点，下面就介绍一下如何在SALV上添加ICON和tooltips。
本例子在SALV的status列中显示红绿灯图标，并根据图标的颜色显示不同的提示信息，方便用户更清晰的阅读SALV，具体方法如下：
1，将为图标ID赋值到Status列上，图标ID的查询方法参照-->如何查找图标ID(ICON ID)等详细信息
2，设定列值为图标-调用cl_salv_columns->get_column ()得到‘Status’列的类引用，然后通过cl_salv_columns->set_icon ()将列设置为显示图标.
3，调用cl_salv_tooltips->add_tooltip()设置图标的提示信息(tooltips)
完整代码如下：

运行后，鼠标悬停在图标(ICON)上会显示相应的提示信息，
以上。
