    String fileName = "fileName";
    

 

 

 

public void exportExcel(String fileurl, String fileName,
            String title, HttpServletResponse response) 
                    throws BiffException, IOException, WriteException
        WritableWorkbook book = getExportHead(fileurl, fileName, response);
        WritableSheet sheet = book.getSheet(0);
        // 定义格式 字体 下划线 斜体 粗体 颜色
        WritableFont sheetTitleFont = new WritableFont(WritableFont.createFont("宋体"), 22,WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE,Colour.BLACK);
        WritableCellFormat sheetTitleCellFormat = new WritableCellFormat(sheetTitleFont); // 单元格定义
        sheetTitleCellFormat.setAlignment(Alignment.CENTRE);
        
        WritableFont cellFont = new WritableFont(WritableFont.createFont("宋体"), 11,WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE,Colour.BLACK);
        WritableCellFormat cellFormat = new WritableCellFormat(cellFont); // 单元格定义
        cellFormat.setWrap(true);
        cellFormat.setAlignment(Alignment.CENTRE);
        sheet.addCell(new Label(0, 0, fileName,sheetTitleCellFormat));//第一行标题
    
        WritableCellFormat writableCellFormat = new WritableCellFormat(cellFormat);
        String[] recordStr = new String[]"serNo","name","age";
        
        int row = 2;//从第2行开始
        
        List<Record> list = 查询数据;
        if(list != null && list.size() > 0)
        for(int i = 0;i < list.size() ;i++)
            for(int col = 0;col < recordStr.length;col++)
                String result = list.get(i).getStr(recordStr[col]);
                sheet.addCell(new Label(col, row+i, result, cellFormat));
                
            
        
        
        book.write();
        book.close();
        
    

 另外：

//TODO mergeCells(列，行，向左合并第几列，向下合并到第几行)
sheet.mergeCells(0, 5, 3, 0);//合并第五行前三列
//TODO Label(列，行，内容，样式)
