Excel文件定位工具创建

背景：女朋友说我excel文件太乱了，找不到，只模糊记得单元格里有啥内容，文件名字是啥忘了，我遇到好多次了，太难找了，我说，那我写个程序帮你找吧，忠诚的程序是不嫌累的。

说干就干，于是第一个版本的出现了：

嗯，它成功的解决了问题找到了文件，但是女朋友说，界面简直太丑了，能不能敢好看点，我不敢也得敢啊。
程序是用Python写的，于是思路是pyside2加pyinstaller搞一下，界面好久没用了，百度去查一下怎么使吧，发现现在都是pyside6了，我想也没多久啊，版本竟然直接从2到6了，真的好久没有关注他了（后来发现这是直接跳过去的）。
思路都有了，中途好多信号和槽，还有多线程都是从这个小项目中学过来的，最终的样子变成这样了。

嗯，废话不多说了，贴代码
