以下是JavaFX中导出Excel的核心代码:

private HSSFWorkbook workbook;


 /* Build Operation Button Area */
        Button exportBn = ButtonBuilder.create().text("导出Excel").prefWidth(80).prefHeight(30).build();
        exportBn.setDefaultButton(true);
        exportBn.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent event) {
                updateQueryResultAllRecords();
                FileChooser fileChooser = new FileChooser();
                fileChooser.setTitle("LaundryService");
                fileChooser.setInitialFileName("laundryrecords.xls");
                fileChooser.getExtensionFilters().add(new FileChooser.ExtensionFilter("XLS Files", "*.xls"));
                File file = fileChooser.showSaveDialog(mRecordDetailStage);
                if(file != null){
                   exportExcel(file.getAbsolutePath());
                     }
            }
        });


private void exportExcel(String fileName) {
        // Declare a work sheet
        workbook = new HSSFWorkbook();
        // Generate a form
        HSSFSheet sheet = workbook.createSheet("LaundryService记录");
        // Set the table for 15 byte default column width
        sheet.setDefaultColumnWidth((short) 15);
        // Create a style
        HSSFCellStyle style = workbook.createCellStyle();
        // The style settings
        style.setFillForegroundColor(HSSFColor.SKY_BLUE.index);
        style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
        style.setBorderBottom(HSSFCellStyle.BORDER_THIN);

        style.setBorderRight(HSSFCellStyle.BORDER_THIN);
        style.setBorderTop(HSSFCellStyle.BORDER_THIN);
        style.setAlignment(HSSFCellStyle.ALIGN_CENTER);
        // Create a font
        HSSFFont font = workbook.createFont();
        font.setColor(HSSFColor.VIOLET.index);
        font.setFontHeightInPoints((short) 12);
        font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);
