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();
    $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();  //设置字体大小
    $objPHPExcel->getActiveSheet()->getStyle('A3')->getFont()->setSize();  //设置字体大小

    $objPHPExcel->getActiveSheet()->getRowDimension('A2')->setRowHeight();//行高
    $objPHPExcel->getActiveSheet()->getRowDimension('A3')->setRowHeight();//行高

    foreach ($data as $k => $v) { 

        $row = $k + ; //行
        $nn = ; 

        foreach ($v as $vv) {
            $col = chr( + $nn); //列
            $obj->setCellValue($col . $row, $vv); //列,行,值
            $nn++;
        }
    }
    //设置列头标题
    for ($i = ; $i < ; $i++) {
        $alpha = chr( + $i);
        //$objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //单元宽度自适应
        $objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setWidth();
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '')->getFont()->setSize();  //设置大小
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中
        $objPHPExcel->getActiveSheet()->getStyle($alpha . '')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); //垂直居中
    } 

   $objPHPExcel->getActiveSheet()->setTitle($sheetname); //题目
   $objPHPExcel->setActiveSheetIndex(); //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(=>array('','5.3数学练习册','*','','','','','','','*'),
                    =>array('','','founder','*','','','','*','*','2019/1/12 21:12:32'),
                    =>array('','','nick','*','','','','','','*')
        );
        $title = array('序号', '练习册名称', '终端用户', '累计数量（二维码）', '个数区间开始', '个数区间结束', '分成', '剩余处理费用', '最终支付', '购买时间'); //设置要导出excel的表头
        exportExcel($list, , $title);

5 然后结果的样子
