在PHP Excel中添加百分比数字格式

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

$value = 0.75; // 百分比数字
$cell = 'A1'; // 单元格位置
$format = '0.00%'; // 百分比格式

$sheet->setCellValue($cell, $value);
$sheet->getStyle($cell)->getNumberFormat()->setFormatCode($format);

$sheet->getStyle($cell)->getFont()->setBold(true);
$sheet->getStyle($cell)->getFont()->setColor(new PHPExcel_Style_Color(PHPExcel_Style_Color::COLOR_RED));
$sheet->getStyle($cell)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('path/to/save/file.xlsx');
