本文实例讲述了java操作excel的方法。分享给大家供大家参考。具体如下：
WritableWorkbook workbook = Workbook.createWorkbook(new File("d:output.xls")); WritableSheet sheet = workbook.createSheet("项目简报", 0); //样式 WritableFont sonti18font = new WritableFont(WritableFont.createFont("宋体"), 18,WritableFont.BOLD);

WritableCellFormat font18Subject = new WritableCellFormat (sonti18font); WritableCellFormat font12Subject = new WritableCellFormat (sonti12font); WritableCellFormat font12SubjectNoBold = new WritableCellFormat (sonti12fontNoBold);
