我尝试使用 Python 包 tabula-py 读取pdf 中的表格，似乎 pdf 表格单元格中的换行符会将原始单元格中的内容分成多个单元格。

我试图搜索各种python包来解决这个问题。似乎 tabula-py 是最稳定的将 pdf 表格转换为 pandas 数据的包。但是，如果这个问题无法解决，我就不得不求助于在线服务，这将为我提供理想的 excel 输出。

from tabula import read_pdf
df=read_pdf("C:/Users/Desktop/test.pdf", pages='all')

我希望 pdf 表可以用这个正确转换。

Tabula 不再有“电子表格”作为选项。而是使用 'lattice' 选项来避免换行符分成新行。像这样的代码：

import tabula

# Read pdf into DataFrame
df = tabula.read_pdf("FDA EPC Text Phrases  (updated March 2018.pdf", pages='all', 
lattice=True)
print(df)

您可以使用值为 'True' 的 'spreadsheet' 选项来省略由换行符引起的多行 NAN 值。

import tabula

# Read pdf into DataFrame
df = tabula.read_pdf("FDA EPC Text Phrases  (updated March 2018.pdf", pages='all', spreadsheet=True)
print(df)
#print(df['Active Moiety Name'])
#print(df['FDA Established Pharmacologic Class\r(EPC) Text Phrase\rPLR regulations require that the following\rstatement is included in the Highlights\rIndications and Usage heading if a drug is a\rmember of an EPC [see 21 CFR\r201.57(a)(6)]: “(Drug) is a (FDA EPC Text\rPhrase) indicated for [indication(s)].” For\reach listed active moiety, the associated\rFDA EPC text phrase is included in this\rdocument. For more information about how\rFDA determines the EPC Text Phrase, see\rthe 2009 "Determining EPC for Use in the\rHighlights" guidance and 2013 "Determining\rEPC for Use in the Highlights" MAPP\r7400.13.'])
