需求：从数据库中读取数据生成下面这个样式的表单
从上图中可以看出，
HSSFWorkbook实现完全可以
那么我们就用它来实现
// 创建一个新的工作簿
HSSFWorkbook workbook = new HSSFWorkbook();
// 创建一个sheet页
HSSFSheet sheet1 = workbook.createSheet("sheet1");
String titel = "充电桩保修单";
创建合并单元格
CellRangeAddress tl = new CellRangeAddress(0 + index, 0 + index, 0, 7);// 下标从0开始 起始行号，终止行号， 起始列号，终止列号
将单元格设置如sheet中
sheet1.addMergedRegion(tl);
设置标题
Row rowTitle = sheet1.createRow(index); Cell cellTitle = rowTitle.createCell(0); cellTitle.setCellValue(titel); //设置标题
以上我们已经实现了简单的样例，依葫芦画照着画出需求图中的样子
