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);
WritableFont sonti12font = new WritableFont(WritableFont.createFont("宋体"), 12,WritableFont.BOLD);
WritableFont sonti12fontNoBold = new WritableFont(WritableFont.createFont("宋体"), 12,WritableFont.NO_BOLD);
WritableCellFormat font18Subject = new WritableCellFormat (sonti18font);
WritableCellFormat font12Subject = new WritableCellFormat (sonti12font);
WritableCellFormat font12SubjectNoBold = new WritableCellFormat (sonti12fontNoBold);
font18Subject.setAlignment(jxl.format.Alignment.CENTRE);
font18Subject.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);
font18Subject.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THIN);
font12Subject.setAlignment(jxl.format.Alignment.LEFT);
font12Subject.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);
font12Subject.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THIN);
font12SubjectNoBold.setAlignment(jxl.format.Alignment.LEFT);
font12SubjectNoBold.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);
font12SubjectNoBold.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THIN);
//样式 end
