好的！我们继续完成剩余的 **3 个管理面板**：`CourseManagementPanel`、`ClassManagementPanel` 和 `EnrollmentManagementPanel`，全部基于你已实现的 DAO 层与数据库结构，支持完整的 **增删改查（CRUD）功能**，并使用 `JTable + 表单输入 + 按钮操作` 的标准 Swing 模式。
---
## ✅ 前提说明
- 所有 DAO 已存在（如 `CourseDaoImpl`, `SchoolClassDaoImpl`, `EnrollmentDaoImpl`）
- 实体类已定义
- 使用 `DefaultTableModel` 动态更新表格
- 支持：添加、修改、删除、刷新、回填、清空
- 字段与数据库严格对齐
