之前写过一篇有关PHP Excel类的教程《PHPExcel使用（导出和导入Excel文件）教程》，可是最近发现这篇文章似乎介绍的有点太简单了，所以在网上找到了《PHPExcel中文帮助手册》,在本文末尾再据此给出一个新的示例。

1.header

[php] header("Content-Type:application/vnd.ms-excel");
header("Content-Disposition:attachment;filename=product.xls");
header("Pragma:no-cache");
header("Expires:0");[/php]

初始化PHPExcel

//Include class

[php]require_once('Classes/PHPExcel.php');
require_once('Classes/PHPExcel/Writer/Excel2007.php');
/*使用PHPExcel 导出 Excel 2007文件时要注意将PHP配置文件中如下功能开启：
*
* PHP version 5.2.0 or higher
* PHP extension php_zip enabled **
* PHP extension php_xml enabled
* PHP extension php_gd2 enabled (if not compiled in)
* php_zip is only needed by PHPExcel_Reader_Excel2007,PHPExcel_Writer_Excel2007,
* PHPExcel_Reader_OOCalc. In other words, if you need PHPExcel to handle .xlsx or .ods files
* you will need the zip extension, but otherwise not.
*/
$objPHPExcel = new PHPExcel();[/php]


//Set properties 设置文件属性

[php]$objPHPExcel->getProperties()->
setCreator("Maarten Balliauw");
$objPHPExcel->getProperties()->
setLastModifiedBy("Maarten Balliauw");
$objPHPExcel->getProperties()->
setTitle("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->
setSubject("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->
setDescription("Test document for Office 2007 XLSX, generated using PHP classes.");
$objPHPExcel->getProperties()->
setKeywords("office 2007 openxml php");

setCategory("Test result file");[/php]


//设置全表的默认样式

[php]$objPHPExcel = new PHPExcel;
// 设置默认的字体样式
$objPHPExcel->getDefaultStyle()->getFont()->setName('Calibri');
// 设置表格字体的大小
$objPHPExcel->getDefaultStyle()->getFont()->setSize(12);[/php]


//批量修改单元格样式

//Add some data 添加数据

示例：
我们将使用PHPExcel创建一个如下图所示的Excel文件（销售报告），使用Calibri字体，默认大小 8pt。单位则使用Euro 欧元。
