方法：在目标单元格中输入公式：=CELL("col",G3)。解读：返回值“7”代表“月薪”列为第7列。二、Excel工作表信息函数：Error.type。功能：返回与错误值对应的数字。语法结构：=Error.type(错误代码)；其中错误代码分别为：“#NULL!”、“#DIV/0!”、“#VALUE!”、“#REF!”、“#NAME?”、“#NUM!”、...
cell21.setCellValue(200); if (sheet != null) { // 获取第五行 Row row = sheet.getRow(4); if (row != null) { // 获取第一列 Cell cell = row.getCell(0); if (cell != null) { // 读值 double value = cell.getNumericCellValue(); System.out.println(value); } } } } } 1...
1、先用正则表达式判断数据是否为数值型,如果为数值型,则设置单元格格式为整数或者小数; 2、然后往单元格中存放数据的时候要设置数据的格式为double类型,如果查看poi的源码HSSFCell.java会发现设置数据的方法如下,所以用setCellValue(double)方法即可。 优化 到了这里,您可能以为万事大吉啊了,其实上面的代码有个陷阱,...

JAVA POI读取Excel中Cell为null的处理 空数据:没有任何编辑过的单元格(非空格) 有时候我们需要对根据每一列的信息进行处理,这里就会出现易错的缺陷。 1.不需要这些空数据 row =sheet.getRow(i);for(Cell c : row) {//处理} 2.需要这些空数据 row =sheet.getRow(i);for(intj=0;j<row.getLastCellNum(...

1 sheet1.GetRow(1).GetCell(1).SetCellValue("新闻");这样第一行就错误报null异常。最后发现模板的问题,因为新建的模板没有什么值所以必须创建一下就搞定了。代码如下修改: 1 2 3 4 5 6 7 8 if (sheet1.GetRow(1) == null) { sheet1.CreateRow(1); } if (sheet1.GetRow(1).GetCell(1) ==...
