# TableStructurer
1. 代码使用
```python
import cv2
from paddlestructure import PaddleStructure,draw_result
table_engine = PaddleStructure(
output='./output/table',
show_log=True)
img_path = '../doc/table/1.png'
img = cv2.imread(img_path)
result = table_engine(img)
for line in result:
print(line)
from PIL import Image
font_path = 'path/tp/PaddleOCR/doc/fonts/simfang.ttf'
image = Image.open(img_path).convert('RGB')
im_show = draw_result(image, result,font_path=font_path)
im_show = Image.fromarray(im_show)
im_show.save('result.jpg')
```
2. 命令行使用
```bash
paddlestructure --image_dir=../doc/table/1.png
```

# 表格结构和内容预测
先cd到PaddleOCR/ppstructure目录下
预测
```python

运行完成后，每张图片的excel表格会保存到table_output字段指定的目录下
评估
