  public static void main(String[] argsthrows IOException, WriteException {
    //Creates a writable workbook with the given file name
    WritableWorkbook workbook = Workbook.createWorkbook(new File("C:/JXL/ColumnFormat.xls"));
    WritableSheet sheet = workbook.createSheet("My Sheet"0);
    
    addCellView(sheet, 04, Colour.ORANGE);
    addCellView(sheet, 18, Colour.WHITE);
    addCellView(sheet, 212, Colour.BRIGHT_GREEN);
    
    //Writes out the data held in this workbook in Excel format
    workbook.write()
    
    //Close and free allocated memory 
    workbook.close()
  }

  private static void addCellView(
      WritableSheet sheet, int col, 
      int widthInChars, Colour colourthrows WriteException {
    
    WritableCellFormat cellFormat = new WritableCellFormat();
    cellFormat.setBackground(colour);
    cellFormat.setBorder(Border.ALL, BorderLineStyle.THIN);
    
    CellView cellView = new CellView();
    cellView.setSize(widthInChars * 256);
    cellView.setFormat(cellFormat);
    sheet.setColumnView(col, cellView);
  }
