thinkphp3.2.3集成phpexcel1.8导出设置单元格合并

1 到这里下载classes里面的文件

https://github.com/PHPOffice/PHPExcel

2 然后放到 thinkphp的vendor 新建一个文件夹 Phpexcel  然后把文件放进去

3 在封装一个函数

function exportExcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') { 
    vendor('Phpexcel.PHPExcel'); //从PHPMailer目录导class.phpmailer.php类文件
    //import("Vendor.excel.phpexcel"); 
    //若没有指定文件名则为当前时间戳 
    if (is_null($savefile)) { 
        $savefile = time(); 
    } 
    //若指字了excel表头，则把表单追加到正文内容前面去 
    if (is_array($title)) { 
        array_unshift($data, $title); 
    } 
 
    $objPHPExcel = new \PHPExcel(); 
    //Excel内容 
    $head_num = count($data); 
 
    $obj = $objPHPExcel->setActiveSheetIndex(0); 
    $obj->mergeCells('A1:K1'); //第一行
    $obj->setCellValue('A1','');  
    $obj->mergeCells('A2:K2'); //第二行
    $obj->setCellValue('A2','好助教支付清单');  
    $obj->mergeCells('A3:K3'); //第三行
    $obj->setCellValue('A3','用户：北交大出版社    时间：2019-01-12至2019-12-12练习册：200种   支付金额：20000元');  
   
    $objPHPExcel->getActiveSheet()->getStyle('A2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中 
    $objPHPExcel->getActiveSheet()->getStyle('A3')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中 
    $objPHPExcel->getActiveSheet()->getStyle('A2')->getFont()->setSize(20);  //设置字体大小
    $objPHPExcel->getActiveSheet()->getStyle('A3')->getFont()->setSize(12);  //设置字体大小
 
    $objPHPExcel->getActiveSheet()->getRowDimension('A2')->setRowHeight(40);//行高
    $objPHPExcel->getActiveSheet()->getRowDimension('A3')->setRowHeight(30);//行高
    
    foreach ($data as $k => $v) { 
        
        $row = $k + 5; //行 
        $nn = 0; 
 
        foreach ($v as $vv) { 
            $col = chr(65 + $nn); //列 
            $obj->setCellValue($col . $row, $vv); //列,行,值 
            $nn++; 
        } 
    } 
    //设置列头标题 
    for ($i = 0; $i < 9; $i++) { 
        $alpha = chr(65 + $i); 
        //$objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //单元宽度自适应  
        $objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setWidth(20);
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '5')->getFont()->setSize(12);  //设置大小 
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '5')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中 
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '5')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); //垂直居中 
    } 
 
   $objPHPExcel->getActiveSheet()->setTitle($sheetname); //题目 
   $objPHPExcel->setActiveSheetIndex(0); //设置当前的sheet   
   header('Content-Type: application/vnd.ms-excel'); 
   header('Content-Disposition: attachment;filename="' . $savefile . '.xls"'); //文件名称 
   header('Cache-Control: max-age=0'); 
   $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); //Excel5 Excel2007 
   $objWriter->save('php://output'); 
}

4 然后调用这个函数

        $list=array(0=>array('1','5.3数学练习册','*','23121','23122','34000','140000','100','149900','*'),
                    1=>array('','','founder','*','23123','23124','4','*','*','2019/1/12 21:12:32'),
                    2=>array('','','nick','*','23124','23125','7','100','149900','*')
        );
        $title = array('序号', '练习册名称', '终端用户', '累计数量（二维码）', '个数区间开始', '个数区间结束', '分成', '剩余处理费用', '最终支付', '购买时间'); //设置要导出excel的表头 
        exportExcel($list, 1, $title);

5 然后结果的样子
