# PaddleX Table Structure Recognition Task Data Annotation Tutorial
## 1. Data Annotation
-For annotating table data, use the [PPOCRLabelv2](https://github.com/PFCCLab/PPOCRLabel/blob/main/README_en.md) tool. Detailed steps can be found in: [【Video Demonstration】](https://www.bilibili.com/video/BV1wR4y1v7JE/?share_source=copy_web&vd_source=cf1f9d24648d49636e3d109c9f9a377d&t=1998)

Table annotation focuses on structured extraction of table data, converting tables in images into Excel format. Therefore, annotation requires the use of an external software to open Excel simultaneously. In PPOCRLabel, complete the annotation of text information within the table (text and position), and in the Excel file, complete the annotation of table structure information. The recommended steps are:

If the default model weights provided by the General Time Series Forecasting Pipeline do not meet your requirements in terms of accuracy or speed in your specific scenario, you can try to further fine-tune the existing model using **your own domain-specific or application-specific data** to improve the recognition performance of the pipeline in your scenario.
#### 4.1 Model Fine-tuning
-Since the General Time Series Forecasting Pipeline includes a time series forecasting module, if the performance of the pipeline does not meet expectations, you need to refer to the [Customization](../../../module_usage/tutorials/time_series_modules/time_series_forecast_en.md#iv-custom-development) section in the [Time Series Forecasting Module Development Tutorial](../../../module_usage/tutorials/time_series_modules/time_series_forecasting_en.md) and use your private dataset to fine-tune the time series forecasting model.

#### 4.2 Model Application
After fine-tuning with your private dataset, you will obtain local model weight files.
