php原生PHPExcel插件导表（附表格合并，加粗居中及加边框换行操作）

PHPExcel是用来操作Office Excel文档的一个PHP类库，它基于微软的OpenXML标准和PHP语言。可以使用它来读取、写入不同格式的电子表格，如 Excel(BIFF) .xls, Excel 2007 (OfficeOpenXML) .xlsx, CSV,Libre/OpenOffice Calc .ods, Gnumeric, PDF, HTML等等。

1首先下载PHPExcel插件 地址：https://github.com/PHPOffice/PHPExcel

2 导入项目中 我的目录结构如下 :


3，此代码可以兼容多种类型的表格：

<?php
namespace action\phpexcel;
/**
* Excel表   导出
*/
class excelAction extends \action
{

/*
*title   excel標題
*column  表格栏目
*OrdersData    表格数据
*footer  表格结束行显示文字
*/
public function  exportexcel($title,$column,$OrdersData,$footer){

/*导入核心类*/
include 'PHPExcel.php';
require_once 'PHPExcel/Writer/Excel5.php';         // 用于其他低版本xls
require_once 'PHPExcel/Writer/Excel2007.php';     // 用于 excel-2007 格式
// Create new PHPExcel object
$objPHPExcel = new \PHPExcel();
// Set properties
$objPHPExcel->getProperties()->setTitle($title);

//set width
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(30);
$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(30);
$objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(30);
$objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('H')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('I')->setWidth(15);
$objPHPExcel->getActiveSheet()->getColumnDimension('J')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('K')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('L')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('M')->setWidth(45);
$objPHPExcel->getActiveSheet()->getColumnDimension('N')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('O')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('P')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('Q')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('R')->setWidth(20);
$objPHPExcel->getActiveSheet()->getColumnDimension('S')->setWidth(20);

$arr=['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'];
//合并单元格
$objPHPExcel->getActiveSheet()->mergeCells('A1:Z1');
//设置表格头部栏目 set table header content
$objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', $title.'  时间:'.date('Y-m-d H:i:s'));
foreach ($column as $k => $v) {
$objPHPExcel->setActiveSheetIndex(0)->setCellValue($arr[$k].'2',$v);
}

// Miscellaneous glyphs, UTF-8
for($i=0;$i<count($OrdersData);$i++){

foreach ($OrdersData[$i] as $k => $va) {
$objPHPExcel->getActiveSheet(0)->setCellValue($arr[$k].($i+3), $va);
}
}
//表格底部栏目
$objPHPExcel->getActiveSheet()->mergeCells('A'.($i+3).':Z'.($i+3));
$objPHPExcel->getActiveSheet(0)->setCellValue('A'.($i+3), $footer);

//  sheet命名
$objPHPExcel->getActiveSheet()->setTitle($title);

/* 生成到浏览器，提供下载 */
ob_end_clean();  //清空缓存
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$title.'('.date('Ymd-His').').xls"');  //日期为文件名后缀
header('Cache-Control: max-age=0');

$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');  //excel5为xls格式，excel2007为xlsx格式
$objWriter->save('php://output');
}
}

（注意：title可以设置文件名称，标题，底部sheet;cloumu表格标题 为以为数组[‘标题1’,’标题2’,’标题3’…,’标题n’]; data数据为二维数组array（0=>array(′′,′′,′′,′′...,′′),2=>array(′′,′′,′′,′′...,′′)......）;footer 设置表格底部的内容）

效果如图



合并单元格：

$objPHPExcel->getActiveSheet()->mergeCells(‘A1:F1’); //合并

$objPHPExcel->getActiveSheet()->unmergeCells(‘A1:F1’); // 拆分

加粗和居中

$objPHPExcel->getActiveSheet()->getStyle(‘A1’)->applyFromArray(

array(

‘font’ => array (

‘bold’ => true

),

‘alignment’ => array(

‘horizontal’ => PHPExcel_Style_Alignment::HORIZONTAL_CENTER

)

)

);

加边框

$objPHPExcel->getActiveSheet()->getStyle(‘A2:F2’)->applyFromArray(

array(

‘borders’ => array(

‘top’ => array(

‘style’ => PHPExcel_Style_Border::BORDER_THIN

)

)

)

);

表格导出时单元格换行效果：数据中需带有换行符（ \n ）

$objPHPExcel->setActiveSheetIndex(0)->getStyle(‘A1’)->getAlignment()->setWrapText(true);
