HSSF font underline

It took a long time to set the underline. Finally, I found POI. The English is not good... I tried it several times to understand it ..... The Chinese are trying to turn all technical documents into Chinese .... Let foreigners also experience the profound and profound Chinese ..

This is the result I want in my project, but below I will give a small example of self-writing that can run successfully independently. If you don't understand it, try it. Of course, you can contact me...

This is a small example written by myself. Import an HSSF jar to run it.
