注意事项：

1.phpexcel下载地址:http://phpexcel.codeplex.com/

2.把Classes目录下的文件（PHPExcel.php和PHPExcel文件夹），放到ThinkPHP\Library\Org\Util目录下（放到其他目录下也可以，只需要能加载类都没有问题）。并把PHPExcel.php 改成PHPExcel.class.php（这一步很重要，你需要加载的php文件都要改成xxx.class.php才行）

3.手动导入类（请注意"\"符号）

import("Org.Util.PHPExcel");

$objPHPExcel = new \PHPExcel();

（本人试过自动加载类，比较麻烦，因为phpexcel的文件都需要加上“namespace Org\Util;”，所以干脆就选择手动加载类）

4.水平居中，垂直居中，高度 等设置。注意放的位置，如果你放在末尾，那么是下一样生效。放到头部，第一行生效（上面代码是第一行生效，如果放到foreach里面就是下一行生效）。

5.import介绍。import("Org.Util.PHPExcel.Writer.Excel2007"); 文件位置：Org\Util\PHPExcel\Writer\Excel2007.class.php

6.图片地址一定要是本地。
objDrawing[objDrawing[k]->setPath('./Upload/'.$img['goods_thumb']);
图片位置：安装目录/Upload/xxx

容易出现的问题: 

1.'class xxx not found' 类导入不成功，可以先在xxx.class.php 放个function ss(){} 然后输出下xx=newxxx;xx=newxxx;xx->ss()输出下看结果。
