ThinkPHP中调用PHPExcel

//引入PHPExcel
vendor('PHPExcel.PHPExcel');

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

//设置文档属性
$objPHPExcel->getProperties()
        ->setCreator("web100.cc")
        ->setLastModifiedBy("web100.cc")
        ->setTitle("Office 2007 XLSX Test Document")
        ->setSubject("Office 2007 XLSX Test Document")
        ->setDescription("Test document generated using PHP classes.")
        ->setKeywords("office 2007 openxml php")
        ->setCategory("Test result file");

//设置当前活动的sheet
$objPHPExcel->setActiveSheetIndex(0);

//选定当前Sheet
$objActSheet = $objPHPExcel->11getActiveSheet();

//设置sheet名字
$objActSheet->setTitle('phpexcel demo');

//由PHPExcel根据传入内容自动判断单元格内容类型
$objActSheet->setCellValue('A1', "Firstname");
$objActSheet->setCellValue('B1', "Lastname");
$objActSheet->setCellValue('C1', "Phone");
$objActSheet->setCellValue('D1', "Fax");
$objActSheet->setCellValue('E1', "Address");
$objActSheet->setCellValue('F1', "ZIP");
$objActSheet->setCellValue('G1', "DATE");

//直接按坐标位置设置值
$objActSheet->setCellValueByColumnAndRow(0, 8, 'firstname');
$objActSheet->setCellValueByColumnAndRow(1, 8, 'lastname');

// 单元格填充值
$objActSheet->setCellValue('A2', "小风");
$objActSheet->setCellValue('B2', "wang");

//设置列宽
$objActSheet->getColumnDimension('C')->setWidth('20');

// 设置行高
$objActSheet->getRowDimension('9')->setRowHeight(20); //第9行，如果setRowHeight(-1)，表示自适应

//设置默认行高
$objActSheet->getDefaultRowDimension()->setRowHeight(15);

// 设置自动换行
$objActSheet->getStyle('A4')->getAlignment()->setWrapText(true);  

// 设置字体
$objActSheet->getStyle('A1')->getFont()->setName('宋体');
// 字号
$objActSheet->getStyle('A1')->getFont()->setSize(12);
// 加粗
$objActSheet->getStyle('A1')->getFont()->setBold(true);

//说明：$objActSheet->getStyle('A1:G10')，可以通过这种方式来选择一片单元格！

// 设置单元格格式
$objActSheet->getCell('C2')->setValueExplicit('861391327543258', PHPExcel_Cell_DataType::TYPE_NUMERIC);

// 日期
$objActSheet->setCellValue('G2', '2008-12-31');

// 时间戳
$time = gmmktime(0,0,0,12,31,2008); // int(1230681600)

// url
$objActSheet->setCellValue('G11', 'www.spalybow.com');
$objActSheet->getCell('G11')->getHyperlink()->setUrl('http://www.spalybow.com');

// 另一个sheet
$objActSheet->setCellValue('G12', 'sheetb');
$objActSheet->getCell('G12')->getHyperlink()->setUrl("sheet://'sheetb'!A1");

// 水平居上
$objActSheet->getStyle('A9:B9')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_TOP);

// 单元格换行
$objActSheet->getStyle('G2:G3')->getAlignment()->setWrapText(true);

// 合并
$objActSheet->mergeCells('A18:E22');

// 固定第一行
$objActSheet->freezePane('A2');

// 保护工作表
$objActSheet->getProtection()->setPassword('PHPExcel');
$objActSheet->getProtection()->setSheet(true);
$objActSheet->getProtection()->setSort(true);
$objActSheet->getProtection()->setInsertRows(true);

//设置边框
$sharedStyle1 = new PHPExcel_Style();
