+## 推荐使用方案
+
+**推荐使用方案1(猴子补丁适配器)**,因为:
+
+1. **无侵入性**:不修改原代码
+2. **完全控制**:可以完全重写处理逻辑
+3. **易于调试**:可以随时开启/关闭
+4. **灵活性强**:可以针对特定场景优化
+
+使用时只需:
+
+````python
+# 在你的脚本开头
+from adapters.table_recognition_adapter import apply_table_recognition_adapter
+
+# 应用适配器
+apply_table_recognition_adapter()
+
+# 正常使用pipeline
+pipeline = create_pipeline("table_recognition_v2")
+results = pipeline.predict(image_path)
+````
+
+这样既保持了原代码的完整性,又能实现你的个性化需求。
