请尝试以下操作：
public static void differentFontTypeInSameCell(){ Workbook wb = new HSSFWorkbook(); Sheet sheet = wb.createSheet("TestSheet"); Cell cell = sheet.createRow(0).createCell(0); Font underlineFont = wb.createFont(); underlineFont.setUnderline(HSSFFont.U_DOUBLE); Font boldFont = wb.createFont(); boldFont.setBoldweight(Font.BOLDWEIGHT_BOLD); Font italicFont = wb.createFont(); italicFont.setItalic(true); CellStyle style = wb.createCellStyle(); style.setFont(underlineFont); cell.setCellStyle(style); RichTextString richString = new HSSFRichTextString("Underline, Bold, Italic"); richString.applyFont(11, 15, boldFont); richString.applyFont(17, 23, italicFont); cell.setCellValue(richString);}看起来像
