一，开发过程中遇到了要用自定义excel表格，记录如下
里面对用的sql对相应的调整即可

方法：

    public function downLoadFile()
    {
        import('Vendor.PHPExcel');
        $phpExcel = new \PHPExcel();
        $phpExcel->getDefaultStyle()->getFont()->setName('宋体');
        $phpExcel->getDefaultStyle()->getFont()->setSize(11);
        $phpExcel->getDefaultStyle()->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
        $phpExcel->getDefaultStyle()->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER);


        $workSheet = $phpExcel->getActiveSheet();
        $workSheet->getColumnDimension('A')->setWidth(8.38);
        $workSheet->getColumnDimension('B')->setWidth(16.88);
        $workSheet->getColumnDimension('C')->setWidth(11.88);
        //合并单元格A1到AH1
        $workSheet->mergeCells('A1:C1');

        //设置边框
        $workSheet->getStyle('A1:C15')->getBorders()->getAllBorders()->setBorderStyle(\PHPExcel_Style_Border::BORDER_THIN);

        //设置行高为42
        $workSheet->getRowDimension(1)->setRowHeight(42);
        //在第一行写入'用户排班表'

        $workSheet->setCellValue('A1', '技能导入表');

        //设置样式
        $workSheet->getStyle('A1')->getFont()->setSize(18);
        $workSheet->getStyle('A1')->getFont()->setBold(true);

        $workSheet->setCellValue('A2', '序号');
        $workSheet->setCellValue('B2', '部门名称');
        $workSheet->setCellValue('C2', '技能 ');
        //插入数据 B列为部门
        $departStr = '';
        $departArr =  M('user_organize')->where(array('level'=>6,'is_del'=>0))->group('judgecode')
            ->order('sort_num desc')->select();
        foreach ($departArr as $ke => $va) {
            $departStr .= $va['name'] . ',';
            $departIds[] = $ke;
        }
        $departStr = rtrim($departStr, ',');
        for($i = 3; $i <= 15; $i++) {
            $objValidation = $workSheet->getCell('B' . $i)->getDataValidation();
            $objValidation->setType( \PHPExcel_Cell_DataValidation::TYPE_LIST );
            $objValidation->setErrorStyle( \PHPExcel_Cell_DataValidation::STYLE_INFORMATION );
            $objValidation->setAllowBlank(false);
            $objValidation->setShowInputMessage(true);
            $objValidation->setShowErrorMessage(true);
            $objValidation->setShowDropDown(true);
            $objValidation->setErrorTitle('输入错误');
            $objValidation->setError('此值不在下拉列表中。');
            $objValidation->setPromptTitle('请从列表中选择');
            $objValidation->setPrompt('请从单元格下拉列表中选择一个值。');
            $objValidation->setFormula1('"' . $departStr . '"');  // Make sure to put the list items between " and "  !!!
            $workSheet->getCell('B' . $i)->setDataValidation($objValidation);
        }

        //合并单元格A35-AH42
        $workSheet->mergeCells('A12:C15');
        //设置A35的文字对齐格式
        $workSheet->getStyle('A12')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
        $workSheet->getStyle('A12')->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_TOP);

        //让单元格内换行符起作用
        $workSheet->getStyle('A12')->getAlignment()->setWrapText(true);
        //定界符结束
        $introduce = <<<EOF
//1、为保证导入数据成功，序号，部门名称和技能必填且要保证正确性哦!（重要）\n 2、同一部门的多个技能用英文符号(,)隔开,技能名不能重复并且当个技能名称不能大于20个字！\n
EOF;
        $workSheet->setCellValue('A12', $introduce);

        $result = \PHPExcel_IOFactory::createWriter($phpExcel, 'Excel2007');
        //返回的对象太大，通过网络传输会有丢失信息情况，所以序列化
        return serialize($result);
    }

调用：

    /*
     * 下载样式
     * */
    public function downLoadFile()
    {
        import('Vendor.PHPExcel');
        $RpcClient  = RpcClient::getInstance();
        $result     = $RpcClient->sendRequest('/User/WorkSkill', 'downLoadFile', []);
        header('Content-Type: application/vnd.ms-excel');
        header("Content-Disposition: attachment;filename=1.xlsx");
        header('Cache-Control: max-age=0');
        $result1 = unserialize($result);
        $result1->save('php://output');
    }
