使用Java格式文本创建Excel

Question

当我下载Excel时，我得到格式为Numbers的单元格我需要格式文本和所有单元格。

try {
            XSSFSheet sheet = workbook.createSheet(eyelash);

            XSSFFont font = workbook.createFont();
            font.setColor(HSSFColor.WHITE.index);
            XSSFCellStyle style = workbook.createCellStyle();
            style.setFont(font);
            style.setFillPattern(FillPatternType.SOLID_FOREGROUND);
            style.setFillForegroundColor(HSSFColor.RED.index);


            String[] header = { "name","surname"};
            XSSFRow rowhead = sheet.createRow((short) 0);
            XSSFCell cell;
            int cellnum = 0;

            for (int i = 0; i < header.length; i++) {
                cell = rowhead.createCell(cellnum);
                cell.setCellValue(header[i]);
                cell.setCellStyle(style);
                cell.setCellType(XSSFCell.CELL_TYPE_STRING);
                cellnum++;
            }

            if (data) {
                int myRowData = 1;
                XSSFRow row = sheet.createRow((short) myRowData);
                ArrayList<GasNomination> list = this.select();

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

                    row.createCell(0).setCellValue(list.get(i).name());
                    row.createCell(1).setCellValue(list.get(i).surname());

                    myRowData++;
                    row = sheet.createRow((short) myRowData);
                }
            }

        } catch (Exception ex) {

        }

我试过cell.setCellType（XSSFCell.CELL_TYPE_STRING）;但是当我打开我的Excel时，我看到formatcell类型数字...

你可以使用DataFormatter，

    System.out.println("started");

    XSSFWorkbook workbook = new XSSFWorkbook();
    XSSFSheet sheet = workbook.createSheet();
    XSSFRow row = sheet.createRow(0);
    XSSFCell cell = row.createCell(0);

    cell.setCellValue(3.14159);
    cell.setCellType(XSSFCell.CELL_TYPE_STRING);

    XSSFDataFormat format = workbook.createDataFormat();
    XSSFCellStyle style = workbook.createCellStyle();
    style.setDataFormat(format.getFormat("Text"));

    cell.setCellStyle(style);

    workbook.write(new FileOutputStream("Test.xlsx"));

    System.out.println("finished");
