二、表格操作
1、读取xls文件
测试文件为:

public void test() throws ioexception, biffexception { // 1、获取文件,创建workbook file file = new file( "d:/test/自动化监测数据上传模板20210525.xls" ); workbook workbook = workbook.getworkbook(file); // 2.获取第一个工作表 sheet sheet = workbook.getsheet( 0 ); // 3.获取表中数据 range[] rangecell = sheet.getmergedcells(); system.out.println( "行:" + sheet.getrows()); system.out.println( "列:" + sheet.getcolumns()); for ( int i = 0 ; i < sheet.getrows(); i++) { for ( int j = 0 ; j < sheet.getcolumns(); j++) { cell cell = sheet.getcell(j, i); string contents = cell.getcontents(); system.out.print(contents + " " ); } system.out.println(); } workbook.close(); } |
输出结果(注意合并单元格处,需要特殊处理):
