Установите для cellStyle ячейку или строку в HSSFWorkbook

Question

Я объявил внутренние переменные таким образом:

FileOutputStream fos;
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet("analyze_result");
Row row = sheet.createRow(rowIndex);
Cell cell = row.createCell(cellIndex);
HSSFCellStyle cs = workbook.createCellStyle();

В середине класса, после того как я соберу некоторые важные данные, я отправляю их следующей функции, но в результате кажется, что никаких изменений в моем Excel не произошло:

private void firstWriteToExcel(DefectFileReader curDF , HSSFSheet sheet , HSSFWorkbook workbook , FileOutputStream fos) throws Exception{

    cs.setWrapText(true);
    cs.setFillForegroundColor(HSSFColor.GREY_25_PERCENT.index);

    if(recipeName.getState() == true){
        row = sheet.createRow(rowIndex - 1);
        row.createCell(cellIndex).setCellValue("Recipe Name: " + curDF.getRecipeName());
        cell.setCellStyle(cs);

    }
    row = sheet.createRow(rowIndex++);
    row.createCell(cellIndex++).setCellValue("inspection index");
    row.setRowStyle(cs);
    if(numberOfDefects.getState() == true){
        System.out.println("in printing to excel");
        row.createCell(cellIndex++).setCellValue("Total Defects");
    }
    if(numberOfDefectsPerDetector.getState() == true){
        ArrayList<String> toOtherFunc = new ArrayList<String>();
        toOtherFunc = curDF.getDetectorNames();
        for(int i=0; i < toOtherFunc.size() ; i++)
            row.createCell(cellIndex++).setCellValue(toOtherFunc.get(i));   
    }
    if(sensetivityName.getState() == true)
        row.createCell(cellIndex++).setCellValue("sensetivity Name");
    if(inspectionDuration.getState()==true)
        row.createCell(cellIndex++).setCellValue("Inspection Duration");

    row.setRowStyle(cs);

    System.out.println("row index is: " + rowIndex + "cell index is: " + cellIndex);
}

private void writeToExcel(DefectFileReader curDF , XSSFSheet sheet , XSSFWorkbook workbook , FileOutputStream fos) throws Exception{

        fontNotForBold.setBold(false);
        csForSecondWrite.setFont(fontNotForBold);
        csForSecondWrite.setFillForegroundColor(new XSSFColor(java.awt.Color.white));
        csForSecondWrite.setFillPattern(CellStyle.SOLID_FOREGROUND);

        csForSecondWrite.setBorderTop(XSSFCellStyle.BORDER_THIN);
        csForSecondWrite.setBorderRight(XSSFCellStyle.BORDER_THIN);
        csForSecondWrite.setBorderLeft(XSSFCellStyle.BORDER_THIN);
    cellIndex = 4;
    row = sheet.createRow(rowIndex++);
    row.createCell(cellIndex++).setCellValue("inspection_" + (rowIndex - 3));
    if(numberOfDefects.getState() == true)
        row.createCell(cellIndex++).setCellValue(curDF.getTotalDefects());
    if(numberOfDefectsPerDetector.getState() == true){
        ArrayList<String> toOtherFunc = new ArrayList<String>();
        int[] toPrintNumber = new int[toOtherFunc.size()];
        toOtherFunc = curDF.getDetectorNames();
        toPrintNumber = curDF.getDefectPerDetector(toOtherFunc);
        for(int i=0; i < toOtherFunc.size() ; i++)
            row.createCell(cellIndex++).setCellValue(toPrintNumber[i]); 
    }
    if(sensetivityName.getState() == true)
        row.createCell(cellIndex++).setCellValue(curDF.getSensetivityName());
    if(LOGloaded == true){
        LogFileReader logReader = new LogFileReader(LOG , curDF.getInspectionEndTime());
        ArrayList<String> toLog = curDF.getRunsIndex();
        String toPrint = "";
        for(int i=0 ; i < toLog.size() ; i = i+2)
            toPrint += toLog.get(i) + ": " + logReader.diagnozeLog(toLog.get(i+1)) + " ";
        if(toPrint.equals(""))
            row.createCell(cellIndex).setCellValue("The data of this run is not in this log!");
        else
            row.createCell(cellIndex).setCellValue(toPrint);
        sheet.autoSizeColumn(cellIndex);
        cellIndex++;

    }
    if(inspectionDuration.getState()==true)
        row.createCell(cellIndex++).setCellValue(curDF.inspectionDuration());


    for (Row row : sheet){
        if( row.getRowNum() > 2){
        for (Cell cell_local : row){
            cell_local.setCellStyle(csForSecondWrite);
        }
        }
