1.准备工作
首先SE11自建一个数据库表（数据元素，域信息请提前建好）
2.编写代码
2.1 新建一个子屏幕
子屏幕中需新定义一个文本输入框，命名为：key_word,新建一个表控件，命名为tab,该表控件的字段选取自建表zchenh001上的所有字段。
可以在“元素清单”界面调整字段显示的宽度，这样更美观：
2.2 拷贝状态栏
SE41 -> 状态
从 程序：SAPLKKBL
状态：STANDARD_FULLSCREEN
到 程序：你的程序
状态：你的程序中需要使用的状态及自定义按钮
2.3 子屏幕的逻辑流
PROCESS BEFORE OUTPUT. MODULE tab_init.
MODULE status_0100.
LOOP AT g_tab_itab
INTO g_tab_wa
WITH CONTROL tab
CURSOR tab-current_line.
MODULE tab_move.
ENDLOOP. PROCESS AFTER INPUT.
MODULE user_command_0100.
LOOP AT g_tab_itab.
CHAIN.
FIELD zchenh001-znum.
FIELD zchenh001-zname.
FIELD zchenh001-zsex.
FIELD zchenh001-zhigh.
ENDCHAIN.
ENDLOOP.
