PHPExcel基本操作：
定义EXCEL实体
即定义一个PHPEXCEL对象，并设置EXCEL对象内显示内容

// Excel开始
// 准备EXCEL的包括文件
// Error reporting 
error_reporting(0);
// PHPExcel 
require_once dirname(__FILE__) . 'PHPExcel.php';
// 生成新的excel对象
$objPHPExcel = new PHPExcel();
// 设置excel文档的属性
$objPHPExcel->getProperties()->setCreator("Sam.c")
             ->setLastModifiedBy("Sam.c Test")
             ->setTitle("Microsoft Office Excel Document")
             ->setSubject("Test")
             ->setDescription("Test")
             ->setKeywords("Test")
             ->setCategory("Test result file");
// 开始操作excel表
// 操作第一个工作表
$objPHPExcel->setActiveSheetIndex(0);
// 设置工作薄名称
$objPHPExcel->getActiveSheet()->setTitle(iconv('gbk', 'utf-8', 'phpexcel测试'));
// 设置默认字体和大小
$objPHPExcel->getDefaultStyle()->getFont()->setName(iconv('gbk', 'utf-8', '宋体'));
$objPHPExcel->getDefaultStyle()->getFont()->setSize(10);

三、输出文件

// 如果需要输出EXCEL格式
if($m_exportType=="excel"){   
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    // 从浏览器直接输出$filename
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
    header("Content-Type:application/force-download");
    header("Content-Type: application/vnd.ms-excel;");
    header("Content-Type:application/octet-stream");
    header("Content-Type:application/download");
    header("Content-Disposition:attachment;filename=".$filename);
    header("Content-Transfer-Encoding:binary");
    $objWriter->save("php://output"); 
}
// 如果需要输出PDF格式
if($m_exportType=="pdf"){
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF');
    $objWriter->setSheetIndex(0);
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
    header("Content-Type:application/force-download");
    header("Content-Type: application/pdf");
    header("Content-Type:application/octet-stream");
    header("Content-Type:application/download");
    header("Content-Disposition:attachment;filename=".$m_strOutputPdfFileName);
    header("Content-Transfer-Encoding:binary");
    $objWriter->save("php://output"); 
}

设置一列的宽度：

$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(15);

设置一行的高度：

$objPHPExcel->getActiveSheet()->getRowDimension('6')->setRowHeight(30);

合并单元格：

$objPHPExcel->getActiveSheet()->mergeCells('A1:P1');

设置A1单元格加粗，居中：

$styleArray1 = array(
  'font' => array(
    'bold' => true,
    'size'=>12,
    'color'=>array(
      'argb' => '00000000',
    ),
  ),
  'alignment' => array(
    'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
  ),
);
// 将A1单元格设置为加粗，居中
$objPHPExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray1);

$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setBold(true);

给特定单元格中写入内容：

$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Hello Baby');

设置单元格样式（水平/垂直居中）：
 

$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
  $objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);

设置单元格样式（黑色字体）：

$objPHPExcel->getActiveSheet()->getStyle('H5')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); // 黑色

设置单元格格式（背景）：

$objPHPExcel->getActiveSheet()->getStyle('H5')->getFill()->getStartColor()->setARGB('00ff99cc'); // 将背景设置为浅粉色

设置单元格格式（数字格式）：

$objPHPExcel->getActiveSheet()->getStyle('F'.$iLineNumber)->getNumberFormat()->setFormatCode('0.000');

给单元格中放入图片：

// 将数据中心图片放在J1单元格内
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('Logo');
$objDrawing->setDescription('Logo');
$objDrawing->setPath('test.jpg');
$objDrawing->setWidth(400);
$objDrawing->setHeight(123);
$objDrawing->setCoordinates('J1');
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());

在单元格中设置超链接：

$objPHPExcel->getActiveSheet()->setCellValue('H8', iconv('gbk', 'utf-8', '燕南天'));
$objPHPExcel->getActiveSheet()->getCell('H8')->getHyperlink()->setUrl('https://www.jb51.net/');

设置单元格边框

$styleThinBlackBorderOutline = array(
    'borders' => array (
       'outline' => array (
          'style' => PHPExcel_Style_Border::BORDER_THIN,  //设置border样式
          //'style' => PHPExcel_Style_Border::BORDER_THICK, 另一种样式
          'color' => array ('argb' => 'FF000000'),     //设置border颜色
      ),
   ),
);
$objPHPExcel->getActiveSheet()->getStyle( 'A4:E10')->applyFromArray($styleThinBlackBorderOutline);

//添加一个新的worksheet 
          $objExcel->createSheet(); 
          $objActSheet = $objExcel->getSheet($s); 
          $objActSheet->setTitle('表'.$GSheet);
