一、工具功能速览
启动工具后，你会看到一个简洁的双栏界面：
左侧：通过标签页切换“概念板块”和“行业板块”，每个板块名称后都紧跟实时涨跌幅（红色代表上涨，绿色代表下跌），让你快速定位强势板块。
右侧：点击左侧任一板块，右侧立即展示该板块的成分股列表，包含股票代码、名称、最新价和涨跌幅，同样用红绿颜色区分涨跌。
二、代码简单介绍
整个程序分为三大模块：
数据模型（StockTableModel）：负责管理股票表格数据及颜色渲染。
工作线程（DataLoader）：处理所有网络请求，通过信号与主线程通信。
主窗口（MainWindow）：搭建界面，连接信号槽，响应用户交互。
这种设计符合MVC（模型-视图-控制器）模式，如果你想增加新的数据维度（如换手率、市盈率），只需修改模型和对应的数据解析部分即可。
三、如何使用？
环境准备
确保你的Python版本≥3.7，然后安装依赖：
pip install pyside6 pandas requests pywencai
pywencai需要依赖node， 建议node18， 不知道怎么操作的可以翻一翻我之前的文章。 或者进群交流。最后这里贴一下完整代码，参考下思路， 具体根据自己的实际情况改造。 备注：如果发现格式有多余的特殊字符，用普通浏览器打开复制应该没问题。 希望我的分享对大家有所帮助。
