Use PHPExcel to create a dropdown in an excel file:

$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);

$configs1 = \"Lorem Ipsum is simply, dummy text of the printing, and typesetting 
industry, Lorem Ipsum has been, the industrys standard, dummy text ever, since the 
1500s, when an unknown printer, took a galley of type, and scrambled it to make, a 
type specimen book, It has survived not only ,five centuries, but also the leap ,into 
electronic typesetting, remaining essentially, unchanged, It was popularised, in the 
1960s with the, release of Letraset sheets, containing Lorem Ipsum ,passages, and 
more recently, with desktop publishing, software like Aldus, PageMaker including, 
versions of Lorem Ipsum,Lorem Ipsum is simply, dummy text of the printing, and 
typesetting industry, Lorem Ipsum has been, the industrys standard, dummy text ever, 
since the 1500s, when an unknown printer, took a galley of type, and scrambled it to 
make, a type specimen book, It has survived not only ,five centuries, but also the 
leap ,into electronic typesetting, remaining essentially, unchanged, It was 
popularised, in the 1960s with the, release12345\";

$objValidation = $objPHPExcel->getActiveSheet()->getCell(\'I2\')->getDataValidation();
$objValidation->setType( PHPExcel_Cell_DataValidation::TYPE_LIST );
$objValidation->setErrorStyle( PHPExcel_Cell_DataValidation::STYLE_INFORMATION );
$objValidation->setAllowBlank(false);
$objValidation->setShowInputMessage(true);
$objValidation->setShowErrorMessage(true);
$objValidation->setShowDropDown(true);
$objValidation->setErrorTitle(\'Input error\');
$objValidation->setError(\'Value is not in list.\');
$objValidation->setFormula1(\'\"\'.$configs1.\'\"\');

$objPHPExcel->setActiveSheetIndex(0);
PHPExcel_Settings::setZipClass(PHPExcel_Settings::PCLZIP);
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$result = $objWriter->save($template_save_file);
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);

下图显示了另外 1022 个字符及其细分下拉列表。

下图显示 1022 个字符工作正常。

问题是在添加更多字符下拉中断后，下拉菜单适用于 1022 个字符。

怎么能增加字数限制？

MS Excel 有其局限性。有时，增加这些限制的唯一方法是给微软写一封“拜托了”的信。但是你到底为什么要使用一个值这么大的 DataValidation 下拉菜单呢？您似乎没有将它用于实际的 DataValidation，而是用作 Cell 注释；那么为什么不实际使用单元格注释呢？

【解决方案1】：

将您的下拉选项添加到另一张表，并使用以下代码从该表中获取数据：

$objValidation->setFormula1('Secondsheet!A2:A100');
