如何使用PHPExcel将百分比数字格式化为Excel百分比？

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

$percentage = 0.75; // 百分比数字
$cellValue = $percentage * 100; // 将百分比数字转换为百分比
$cell = 'A1'; // 单元格位置
$objPHPExcel->getActiveSheet()->setCellValueExplicit($cell, $cellValue, PHPExcel_Cell_DataType::TYPE_NUMERIC);

$style = $objPHPExcel->getActiveSheet()->getStyle($cell);
$style->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_PERCENTAGE);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('output.xlsx');
