Java Poi 在Excel中输出特殊符号的实现方法

时间:2020-07-17 15:59     来源/作者:浮生-

最近的工作围绕报表导出,并没有集成相应的报表插件,只是使用了Poi。其中有一个需求,Excel中导出特殊符号,如√、×等。在网上找寻了许久,没有相关资料,故记录分享一下。

思考良久,走了不少弯路,最后受 System.out.println() 启发,实现方式真的超级简单。每一个特殊符号,都对应一个Unicode编码,我们只需要将特定的符号,转变成Unicode编码,进行输出即可。

Java Poi 在Excel中输出特殊符号的实现方法

相应的代码输出:

cell.setCellValue("\u221A");

另附自己编写的Excel工具类,支持单表、主子表(可定制主表在前还是在后)、图片、特殊符号等。

Java Poi 在Excel中输出特殊符号的实现方法

但仍遇到一个问题,主子表结构导出,如果图片在主表,合并行之后,图片并不会居中,并且第一行会被撑开,有没有比较简单的方式进行处理(不想重新计算锚点,然后定高输出)?
