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ThinkPHPVendor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LibAction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：

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

            $objPHPExcel->getActiveSheet(0)->setCellValue("D".($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"]);

            $objPHPExcel->getActiveSheet(0)->setCellValue("I".($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：
