php PHPEXcel导出

1获取数据，2组装数据，3生成文件。

注意：无法使用ajax生成导出。

$settlement = \Yii::$app->request->get('settlement');
        $save_folder_file = \Yii::$app->request->get('folder_file');
        $objPHPExcel = new PHPExcel();
        $items = Finance::getSettlementById($settlement);
        //>>1定义表头
        $objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', '订单号')
            ->setCellValue('B1', '客户名称')
            ->setCellValue('C1', '要求')
            ->setCellValue('D1', '订单标售金额(元)')
            ->setCellValue('E1', '订单实售金额(元)')
            ->setCellValue('F1', '创建时间');

        //>>2 设置内容 从第二行开始
        $i = 2;
        foreach ($items as $item) {
            $objPHPExcel->setActiveSheetIndex(0)
                ->setCellValue('A' . $i, $item['Code'])
                ->setCellValue('B' . $i, $item['CustomerName'])
                ->setCellValue('C' . $i, $item['Require'])
                ->setCellValue('D' . $i, $item['Amount'])
                ->setCellValue('E' . $i, $item['DueAmount'])
                ->setCellValue('F' . $i, Tools::getDatetimeFormat($item['CreateTime']));
            $i++;
        }

        $objActSheet = $objPHPExcel->getActiveSheet();
        $objActSheet->getColumnDimension('A')->setAutoSize(true);
        $objActSheet->getColumnDimension('D')->setWidth(18);
        $objActSheet->getColumnDimension('E')->setWidth(18);
        $objActSheet->getColumnDimension('F')->setWidth(18);

        $time = date('Y-m-d H:i:s', time());
        $file_name = '订单详情' . $time . '.xlsx';
