phpexcel导出下拉框，超过255字符不显示的问题处理

news 来源：原创 2025/6/19 19:09:30

用php生成excel模板，并设置下拉框的选项。如果选项太多，可能导致下拉框不显示的问题。下面会给出示例，以及解决方案，支持生成包含大量数据的下拉框。

// $info 为下拉框的数数据，['男','女','保密']
function exportDataSelectOptions ($info){
//文件名称
$filename = 'AAAA导入模板';

//excel表格列名
$header = [['名字',30],['手机号',25],['邮箱',25],['性别',10],['所在地址',26]];

//需要制作的下拉框文件
$spectials = [   ['column'=>'D','options'=>['男','女','保密'] ],
            ['column'=>'E','options'=>$info]];

//样例
$data = [
            ['测试样例1','13665663533','13665663533@qq.com','女',$info[0]],
            ['测试样例2','13665663532','13665663532@qq.com','男',$info[0]],
            ['测试样例3','13665663513','13665663513@qq.com','男',$info[0]],
        ];

ini_set("error_reporting","E_ALL & ~E_NOTICE");

require_once '../phpexcel/Classes/PHPExcel.php'; //初始化PHPExcel(),不使用模板 

$objPHPExcel = new PHPExcel();

$objPHPExcel->setActiveSheetIndex(0);

//头部样式
$objPHPExcel->getDefaultStyle()->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
$objPHPExcel->getDefaultStyle()->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$hk = 0; 

//所有单元格（行）默认高度
$objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(25);

// 自动换行
// $objPHPExcel->getActiveSheet()->getStyle( 'A1:L100')->getAlignment()->setWrapText(true);

// 设置特有的表格样式
$styleThinBlackBorderOutline = array( //边框线
    'borders' => array(
        'allborders' => array( //设置全部边框
            'style' => \PHPExcel_Style_Border::BORDER_THIN //粗的是thick
        ),
    ),
);
//设置边框
$objPHPExcel->getActiveSheet()->getStyle( 'A1:L100')->applyFromArray($styleThinBlackBorderOutline);

//合并单元格（如果要拆分单元格是需要先合并再拆分的，否则程序会报错）
$objPHPExcel->getActiveSheet()->mergeCells('A1:L1');

//拆分单元格;
// $objPHPExcel->getActiveSheet()->unmergeCells('B7:D7'); 

// 设置内容 
$objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1','标题：XXXXXXX');
// 设置字体样式
// $PHPExcel->getActiveSheet()->getStyle('A1')->getFont()->setName('宋体');
// 设置文字加粗
// $objPHPExcel->getActiveSheet()->getStyle('A1')->getFont()->setBold(true);  
// 设置文字大小
// $objPHPExcel->getActiveSheet()->getStyle('A1')->getFont()->setSize(18);
// 设置文字水平居中
$objPHPExcel->getActiveSheet(0)->getStyle('A1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
// 设置文字垂直居中
$objPHPExcel->getActiveSheet(0)->getStyle('A1')->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_BOTTOM);
// 设置自动换行
// $PHPExcel->getActiveSheet(0)->getStyle('A2')->getAlignment()->setWrapText(true);


//写入头部
foreach ($header as $k => $v)
{
    $colum = \PHPExcel_Cell::stringFromColumnIndex($hk);
    $objPHPExcel->setActiveSheetIndex(0)->setCellValue($colum.$rowindex, $v[0]);
    $objPHPExcel->getActiveSheet(0)->getColumnDimension($colum )->setWidth($v[1]);

    $hk += 1;
}

$objActSheet = $objPHPExcel->getActiveSheet(0);

// 新建工作表  -->保存下拉框数据来源
$objPHPExcel->createSheet(); 
$subObject = $objPHPExcel->getSheet(1);
$subObject->setTitle("data");

$subcolumn = ['A','B','C','D','E','F','G','H','I','J','K'];
//设置下拉框
foreach($spectials as $k => $spectial)

    //保存下拉框内容到新建的工作表中
    $list = $spectial['options'];

        foreach ($list as $i => $d) {

            $subObject->setCellValue($c,$d); 
        } 
    }

    //下拉框写入开始行数
    $n = 2;
    // 我这里设置100行，可自行设置
    while($n < 101) {
        $objValidation = $objActSheet->getCell($spectial['column'].(string)$n)->getDataValidation(); //这一句为要设置数据有效性的单元格
        // $objValidation的各项设置参数可详见phpexcel文件，
        // 目录大概为/.../phpoffice/phpexcel/Classes/PHPExcel/Writer/Excel5/Worksheet.php 
        // 2767行 方法名：writeDataValidity
        $objValidation -> setType(\PHPExcel_Cell_DataValidation::TYPE_LIST)
        -> setErrorStyle(\PHPExcel_Cell_DataValidation::STYLE_STOP)
        -> setAllowBlank(true)

        // -> setFormula1('"'.$optionsString.'"'); //如果下拉框数据来源少,可使用此方法,无需新建表格
        $n++;
