根据以下给的数据库表结构，用PyQt5+MySQL实现增删改查，表结构如下：CREATE TABLE `register_copy1` ( `id` int NOT NULL AUTO_INCREMENT, `register_type` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `tooth_number` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `hospital_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `doctor_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `patient_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `color_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `category_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `price` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `tooth_a` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `tooth_b` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `tooth_c` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `tooth_d` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `number` int NOT NULL, `amount_of_money` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `delivery_date` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `register_date` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `remark` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `total_amount` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, PRIMARY KEY (`id`) USING BTREE ) ENGINE = InnoDB AUTO_INCREMENT = 48 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic; SET FOREIGN_KEY_CHECKS = 1;

我可以回答这个问题。要实现增删改查，需要使用PyQt5和MySQL。首先，需要连接到MySQL数据库，然后创建一个表格模型，并将其与表格视图关联。接下来，可以使用模型的方法来添加、删除和修改数据。查询数据可以使用SQL语句来执行。具体实现细节可以参考PyQt5和MySQL的文档。
