说明：  应用Ehlib导出显示数据的源代码，一直以来delphi配合Ehlib是非常好的数据库编程排档，但是DBGRID输出到EXCEL等格式却是十分麻烦的事情。此代码应用EHLIB自身功能可直接输出各类排版格式。应用十分简单。
(derived data show the source code, delphi has been with Ehlib is a very good database programming stall, But Input output to Excel format is very troublesome thing. Application of this code EHLIB own functions can be directly output types typesetting format. Application is very simple.)
