目前作者已知的EXCEL输出方式有3种：
1.GUI_DOWNLOAD函数输出（适用于简单无格式要求的输出）。
2.OLE输出（适用于对EXCEL格式输出有特殊要求的，但是因其填充数据和设置格式是基于一个个单元格去操作来完成的，所以速度很慢，在下面的DEMO中，202行6列的数据输出需要用时2分钟左右）。
3.DOI输出（可以嵌入屏幕容器中直接输出EXCEL，且所有方法封装在类中，编写起来更加简单）。
个人感觉OLE的学习最好方式是设置EXCEL输出为前端显示模式，然后一句句弄懂每句OLE语句的意义，知道每一个OLE语句等同于在EXCEL中做了什么样的操作。
例如你写完
CREATE OBJECT V_EXCEL 'EXCEL.APPLICATION'. SET PROPERTY OF V_EXCEL 'VISIBLE' = 1.
你知道此时执行是打开了EXCEL应用，但是其中没有任何工作页，如下图：
当你在加上OLE语句
* "新建一个工作区WORKBOOK CALL METHOD OF V_EXCEL 'WORKBOOKS' = V_BOOK. CALL METHOD OF V_BOOK 'ADD'.
你知道此时创建了一个工作区，其中自动插入了一个工作页，且其为激活状态，如下图：
当你像这样一句句的做完一个DEMO之后，相信你应该能熟练应用OLE来输出EXCEL。
下面给出一个OLE的简单DEMO程序：
