今天看到一个程序是从报表按钮点击，生成一个word到本地。word中有表格，还有报表里的一些参数，
同事讨论说只见过下载成excel样式的，还没见过word的。然后就百度了一下，发现了上面的地址。
这段代码原本是将一个简单的表格样式写成html格式（原文好像说是xml格式），然后用GUI_DOWNLOAD函数加后缀名
强行下载到本地，所以在函数中将后缀名改成什么格式，就显示成什么格式。
doc-->word格式
html-->网页显示
原本代码中的表格内容是写死的，和html文件内容放在一起，abap里是用宏加进内表的，宏里面好像没法打断点，
那段html文本我尝试打断，想将其中的表格内容换成变量显示，然后失败了，只能一行一行append才能加变量。
代码如下（注释部分为源代码，表格里面的内容写死了）可以直接运行.

GUI_DOWNLOAD比较万能，这个似乎什么格式放上去都能原样down下来。
但是这样去生成一个word感觉很业余，比较专业的方法是用ole实现：

....这个看上去略麻烦，等有空仔细研究了再更新吧。
