Java 无法通过poi打印范围内单元格的值
我有下面的java程序，它也在尝试通过JavaPOI读取excel表，首先看到下面的excel表格式，如下所示Java 无法通过poi打印范围内单元格的值,java,apache-poi,Java,Apache Poi,我有下面的java程序，它也在尝试通过JavaPOI读取excel表，首先看到下面的excel表格式，如下所示 abcRef 21 ABC 20 ERT 60 FGT 57 abcRef SMS Seal Total 12 45 DRT 3000 23 36 QWE 2000 subtotal

- 1） 遇到任何空行
- 2） 任何单元格值为的行 小计
- 3） 遇到的任何标题单元格都是 （abcRef+SMS+印章+总计）
