Hi @zyc1128, it sounds like you need help with a specific PDF. Can you share the PDF here, along with the code you're using, and a longer explanation of what difficulty you're having?

Yes, that upload worked, thanks. Re. your question about tables, when I run this code:

# To remove the watermarking text
filtered = pdf.pages[2].filter(lambda obj: not (obj.get("fontname") == "MWRYEA+NSimSun"))

for i, table in enumerate(filtered.extract_tables()):
    print(f"=== Table {i} ===")
    print(table)
    print("\n---\n")

... I get this:

=== Table 0 ===
[['款式', '场景图', '拉手示意图', '备注'], ['芬兰', '', '', '1.门板、装饰板：18mm厚，平板无造型，四周1.3mm同色PVC封边；\n2.地柜可配合潘多拉铝线箱体使用；\n（CB365/366颜色可选氧化色、巧克力或铜拉丝色）；'], ['芬兰II', '', '', '1.门板：18mm厚，平板无造型，三边1.3mm同色PVC封边，拉手边\n0.45mm巧克力铝色（FL120系列拉手）/氧化铝色PVC封边（FL033\n系列拉手）；\n2.装饰板：18mm厚，平板无造型，四周1.3mm同色PVC封边；']]

Does that work for you?

谢谢，很有帮助！我用了你这个示例的filtered.extract_text()：
texts = ""
for text in enumerate(filtered.extract_text()):
texts=texts+text[1]
print(texts)
提取了文字和table,这个texts是一个类似于string的结构，如何让这里面table内容以类似于dataframe的表现形式存在于这个texts中？就像原PDF一样，看上去就是去掉了table里的横线和竖线？

我用一样的代码提取另一个PDF的文字，它又把一些
Uploading JS-B5-04-026D-博洛尼家具-新伯尔尼亚系列型录-V1.2.pdf…
没用的斜的字提取出来了

To extract tables, you'll want to use the .extract_table(...) or .extract_tables(...) methods. To convert those into DataFrames, you can pass the nested-list representation of the table to pandas.DataFrame(...). E.g.:

import pandas as pd
import pdfplumber

pdf = pdfplumber.open("path.pdf")
page = pdf.pages[0]
table = page.extract_table()
df = pd.DataFrame(table)
