准备工作：
1.下载phpexcel1.7.6类包；
2.解压至TP框架的ThinkPHP\Vendor目录下，改类包文件夹名为PHPExcel176，目录结构如下图；
编写代码(以一个订单汇总数据为例)：
1. 创建数据库及表;
2. 创建tp项目，配置项目的数据库连接，这些基本的就不说了；
3. 在项目的Lib\Action下创建一个新的类文件ExportStatisticsAction.class.php，然后在 index方法中实现excel导出；
4. 导出方法的步骤：
①查询数据
②导入phpexcel类库
③创建excel对象并设置excel对象的属性
④设置excel的行列样式(字体、高宽、颜色、边框、合并等)
⑤绘制报表表头
⑥将查询数据写入excel
⑦设置excel的sheet的名称
⑧设置excel报表打开后初始的sheet
⑨设置输出的excel的头参数及文件名
⑩调用创建excel的方法生成excel文件
代码如下：

class ExportStatisticsAction extends Action {
public function index(){
$model= D("OrdersView");
$OrdersData= $model->select(); //查询数据得到$OrdersData二维数组
vendor("PHPExcel176.PHPExcel");
// Create new PHPExcel object
$objPHPExcel = new PHPExcel();
// Set properties

$objPHPExcel->getActiveSheet()->getStyle('A'.($i+3).':J'.($i+3))->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getActiveSheet()->getRowDimension($i+3)->setRowHeight(16);
}
// sheet命名
$objPHPExcel->getActiveSheet()->setTitle('订单汇总表');
// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);
// excel头参数
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="订单汇总表('.date('Ymd-His').').xls"'); //日期为文件名后缀
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); //excel5为xls格式，excel2007为xlsx格式
$objWriter->save('php://output');
}
}5.调用导出方法直接 http://项目/index.php/ExportStatistics/index，项目中调用直接__APP__/ExportStatistics/index,生成的报表是下载方式来保存。phpexcel1.7.6没有发现什么编码问题，速度也很快，注意导出的方法中不能有任何页面输出信息或调试信息，否则导出的excel会提示格式不对。效果如下：
导出报表
