当Python tabula-py表格中有换行符时，如何读取pdf中的表格？

Question

我尝试使用Python包tabula-py来读取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。

我尝试搜索各种python包来解决这个问题。看来 tabula-py 是将 pdf 表转换为 pandas 数据的最稳定的包。但是，如果这个问题无法解决，我必须求助于在线服务，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')

我期望 pdf 表可以用这个正确转换。

Answer 1

您可以使用值为“True”的“电子表格”选项来省略由换行符引起的多行 NAN 值。

\n\n

import tabula\n\n# Read pdf into DataFrame\ndf = tabula.read_pdf("FDA EPC Text Phrases  (updated March 2018.pdf", pages=\'all\', spreadsheet=True)\nprint(df)\n#print(df[\'Active Moiety Name\'])\n#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)]: \xe2\x80\x9c(Drug) is a (FDA EPC Text\\rPhrase) indicated for [indication(s)].\xe2\x80\x9d For\\reach listed active moiety, the associated\\rFDA EPC text phrase is included in this\\rdocument.
