实现步骤：
一：在http://phpexcel.codeplex.com/下载最新PHPExcel放到Vendor下，注意位置：ThinkPHPExtendVendorPHPExcelPHPExcel.php。
二：导出excel代码实现

    function expUser()
    {
        $xlsName  = "User";
        $xlsCell  = array(
        array('userid','账号序列'),
        array('title','标题'),
        array('city_id','地区'),
        array('sex','性别'),
        array('age','年龄'),

        array('month_salary','月收入'),
        array('weixin','微信号'),
        array('pubtime','提交时间')
        );
        $xlsModel = M('meet');

        $xlsData  = $xlsModel->Field('userid,title,city_id,sex,age,height,telephone,education_id,professional,month_salary,weixin,pubtime')->select();
        foreach ($xlsData as $k => $v)
        {
            $xlsData[$k]['sex']=$v['sex']==1?'女':'男';
        }
        $this->exportExcel($xlsName,$xlsCell,$xlsData);
            
    }


    /*导出方法*/
    public function exportExcel($expTitle,$expCellName,$expTableData)
    {
        $xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称
        $fileName = $_SESSION['account'].date('_YmdHis');//or $xlsTitle 文件名称可根据自己情况设定
        $cellNum = count($expCellName);
        $dataNum = count($expTableData);

        vendor("PHPExcel.PHPExcel");
            
        $objPHPExcel = new PHPExcel();
        $cellName = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','AA','AB','AC','AD','AE','AF','AG','AH','AI','AJ','AK','AL','AM','AN','AO','AP','AQ','AR','AS','AT','AU','AV','AW','AX','AY','AZ');

        $objPHPExcel->getActiveSheet(0)->mergeCells('A1:'.$cellName[$cellNum-1].'1');//合并单元格
        // $objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', $expTitle.'  Export time:'.date('Y-m-d H:i:s'));
        for($i=0;$i<$cellNum;$i++)
        {
            $objPHPExcel->setActiveSheetIndex(0)->setCellValue($cellName[$i].'2', $expCellName[$i][1]);
        }
        // Miscellaneous glyphs, UTF-8
        for($i=0;$i<$dataNum;$i++)
        {
            for($j=0;$j<$cellNum;$j++)
            {
                $objPHPExcel->getActiveSheet(0)->setCellValue($cellName[$j].($i+3), $expTableData[$i][$expCellName[$j][0]]);
            }
        }

        header('pragma:public');
        header('Content-type:application/vnd.ms-excel;charset=utf-8;name="'.$xlsTitle.'.xls"');
        header("Content-Disposition:attachment;filename=$fileName.xls");//attachment新窗口打印inline本窗口打印
        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
        $objWriter->save('php://output');
        exit;
    }
