$objPHPExcel->getActiveSheet()->getStyle('A3')->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getActiveSheet()->getStyle('A3')->getBorders()->getLeft()->getColor()->setARGB('FF000000');
$objPHPExcel->getActiveSheet()->getStyle('A3')->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getActiveSheet()->getStyle('A3')->getBorders()->getBottom()->getColor()->setARGB('FF000000');

$objPHPExcel->getActiveSheet()->getStyle('A3')->getBorders()->getRight()->getColor()->setARGB('FF000000');

$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1','')
            ->setCellValue('A2','编号：' . $BNum)
            ->setCellValue('B3',$Cz)
            ->setCellValue('G19',number_format($Czcb, 2, '.', ''))
            ->setCellValue('C20',round($Cxl,2).'%')
            ->setCellValue('E22',"鉴定评估师(签章)". $Jdpgs ."\n复核人(签章)\n"."评估日期：".date("Y年m月d日",strtotime($Jdpgs_de)) );

// Rename sheet
$objPHPExcel->getActiveSheet()->setTitle('二手车鉴定评估报告单');

// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);

// Redirect output to a client's web browser (Excel5)

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('../excel/'. $Pg_Excel .'');

如果想生成多个sheet

$objPHPExcel1 = $objPHPExcel->createSheet(1);

$objPHPExcel1->setTitle('表2');

$objPHPExcel1->setCellValue('A1','');

//第二张表的操作都不需要用getActiveSheet()方法了
$objPHPExcel1->getRowDimension(1)->setRowHeight(80);
