完整的thinphp+phpexcel实现excel报表的输出(有图有效果)

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：

        $model= D("OrdersView");
        $OrdersData= $model->select();  //查询数据得到$OrdersData二维数组

        //合并cell
        $objPHPExcel->getActiveSheet()->mergeCells('A1:J1');

        // set table header content

        // Miscellaneous glyphs, UTF-8
        for($i=0;$i<count($OrdersData)-1;$i++){
            $objPHPExcel->getActiveSheet(0)->setCellValue('A'.($i+3), $OrdersData[$i]['id']);
            $objPHPExcel->getActiveSheet(0)->setCellValue('B'.($i+3), $OrdersData[$i]['realname']);

            $objPHPExcel->getActiveSheet(0)->setCellValue('D'.($i+3), toDate($OrdersData[$i]['create_time'])); //这里调用了common.php的时间戳转换函数
            $objPHPExcel->getActiveSheet(0)->setCellValue('E'.($i+3), $OrdersData[$i]['require_product']);
            $objPHPExcel->getActiveSheet(0)->setCellValue('F'.($i+3), $OrdersData[$i]['require_count']);
            $objPHPExcel->getActiveSheet(0)->setCellValue('G'.($i+3), $OrdersData[$i]['require_time']);
            $objPHPExcel->getActiveSheet(0)->setCellValue('H'.($i+3), $OrdersData[$i]['product_bom_encoding']);
            $objPHPExcel->getActiveSheet(0)->setCellValue('I'.($i+3), $OrdersData[$i]['delivery_time']);
            $objPHPExcel->getActiveSheet(0)->setCellValue('J'.($i+3), $OrdersData[$i]['delivery_memo']);
            $objPHPExcel->getActiveSheet()->getStyle('A'.($i+3).':J'.($i+3))->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
            $objPHPExcel->getActiveSheet()->getStyle('A'.($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：
