正如文章所述 - 创建的样式仅在我打开创建的 *.xls 文件并双击格式化的单元格后才适用。

 public HSSFWorkbook makeWorkbookExc(List<String[]> allValues, List<String> captions, Integer[] order,
        List<Integer> numTypeColumns,List<Integer> dateTypeColumns, final container container, final List<ErrorContainer> errors) {
    HSSFWorkbook workbook = new HSSFWorkbook();

    HSSFFont fontBold = workbook.createFont();
    fontBold.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);
    fontBold.setFontHeightInPoints((short) 11);
    HSSFCellStyle styleBold = workbook.createCellStyle();
    styleBold.setFont(fontBold);

    HSSFFont font = workbook.createFont();
    font.setFontHeightInPoints((short) 11);
    font.setBoldweight(HSSFFont.BOLDWEIGHT_NORMAL);
    HSSFCellStyle style = workbook.createCellStyle();
    style.setFont(font);
    style.setWrapText(true);
    HSSFDataFormat dataFormat = workbook.createDataFormat();
    HSSFCellStyle dateStyle = ((HSSFWorkbook)workbook).createCellStyle();
    dateStyle.setDataFormat(dataFormat.getFormat("dd.mm.yyyy hh:mm"));
    HSSFSheet baseDataSheet = workbook.createSheet();
    int rowNr = 0;

    Row row = baseDataSheet.createRow(rowNr++);


    for(int i=0; i< allValues.size(); i++) {

        row = baseDataSheet.createRow(rowNr++);
        String[] dataFields = allValues.get(i);

        for (int index = 0 ; index < order.length; index++){
            Cell nmrCell = row.createCell(index);   
            String value = dataFields[order[index]];
            if(value.contains("<br>")){
                //listagg spaces fix
                String trimSpaces = value.trim().replaceAll(" +"," ");
                value = trimSpaces;
                String replace = value.trim().replaceAll("<br> ","\n\n");
                value = replace;
            }

            if (!numTypeColumns.isEmpty() && !"".equals(value) && numTypeColumns.contains(index+1)){
                double valueDouble = Double.parseDouble(value);
                nmrCell.setCellType(HSSFCell.CELL_TYPE_NUMERIC);
                nmrCell.setCellValue(valueDouble);
            } else if(!numTypeColumns.isEmpty() && !"".equals(value) && dateTypeColumns.contains(index+1)){
                nmrCell.setCellStyle(dateStyle);
                nmrCell.setCellValue(value);
            }else
                nmrCell.setCellStyle(style);
                nmrCell.setCellValue(value);


        }

    }

    return workbook;
}

有什么解决办法吗？

所以答案是添加日期解析，因为我最初将值作为字符串

SimpleDateFormat date = new SimpleDateFormat("yyyy-mm-dd hh:mm:ss");
                try {
                    Date dateVal = date.parse(value);
                    nmrCell.setCellStyle(dateStyle);
                    nmrCell.setCellValue(dateVal);
                } catch (ParseException e) {
                    nmrCell.setCellValue(value);
                }

请检查 的数据类型cell.SetCellValue。货币数据格式化程序的示例，数据类型将是双精度cell.SetCellValue(double)或日期，它将是日期。cell.SetCellValue(String)可能会导致问题
