1.随时取数随时显示，显示表 lt_item的数据，每个字段都显示
2.列名称需要每一个单独设置
"重新设置列名称 go_alv->get_columns( )->get_column( 'KDAUF' )->set_long_text( '销售订单' )." go_alv->get_columns( )->get_column( 'AUFNR' )->set_long_text( '生产订单' )." go_alv->get_columns( )->get_column( 'BDMNG' )->set_long_text( '需求数量' )."3.窗口大小参数有四个，分别是左上角的X坐标，右下角的X坐标，左上角的Y坐标，右下角的Y坐标
IF go_alv IS BOUND."设置窗口大小与位置- go_alv->set_screen_popup( start_column = 30 end_column = 80 start_line = 5 end_line = 15 ). go_alv->display( ). ENDIF.全部代码如下，一般是双击按钮调用这个perfoem。
