这是一个约 500 行的 Python 项目，展示了如何使用 PyQt 构建一个功能完善的人员信息管理系统。对于初学者来说，这是练手提升能力的优秀案例。
系统主界面预览：
核心界面搭建逻辑
在 init_ui 方法中，我们主要完成了三个部分的工作：基础控件布局、数据表格初始化以及交互事件绑定。代码结构清晰，便于后续扩展。
首先设置窗口标题和固定尺寸，确保界面在不同分辨率下保持整洁。字体统一使用黑体 12 号，保证可读性。
接下来是输入区域的布局。我们使用了 QLabel 配合 QLineEdit 或 QComboBox 来收集用户信息。注意字段的排列顺序，将姓名、性别、身份证等关键信息放在第一行，电话、部门、专业等次要信息紧随其后。对于日期字段，直接使用 QDateTimeEdit 并开启日历弹窗，这样用户选择生日时体验更友好。
