1. 写在前面的话

首先，第一次翻译该文档，漏洞百出，希望大家给点意见和指导。

phpExcel官网指出：PHPExcel是基于OPENXML标准，使用PHP读写并创建Excel文件电子表格的引擎。

该项目为php编程语言提供了一系列允许你读写不同文件格式的电子表格的类，像Excel(BIFF).xls、Excel 2007 (Office OpenXML).xlsx、CSV、Libre/OpenOffice Cacl .ods、Gnumeric、PDF、HTML等等。该项目围绕微软的OpenXML标准和PHP建立。

该项目提供一系列新特性，如设置电子表格元数据（作者，标题，描述，……）、多个工作表、不同的字体及字体样式、单元边框、填充、渐变、添加图片到电子表格、计算公式、转换成多种文件类型！
