// 	// 注意：实际应用中，主数据通常从ERP系统同步，不需要默认值

//
// 在包的init()函数中注册：
// func init() {
// 	RegisterDefaultValues(registerProductDefaults)
// }

// 注意：要为其他表添加默认值，请遵循以下步骤：
// 1. 在任意表文件中定义一个函数：func myTableDefaults(dbFactory *database.DBFactory) error
// 2. 在函数的init()中调用RegisterDefaultValues注册该函数
// 3. 确保函数在包初始化时被注册（init()函数会自动执行）
// 4. 在应用启动时调用tables.RegisterAllDefaults(dbFactory)执行所有注册
