How can I get pdfplumber to recognise paragraphs in a cell?

Question

I am using pdfplumber for table-extraction. By extracting a cell with multiple paragraphs pdfplumber recognises each paragraph as row, but they are in a cell and should be seen as one row. I tried some table_settings in the extract_table function, but could not change output. The code I used:

import pdfplumber


with pdfplumber.open(PDFPfad) as pdf:
    Seite = pdf.pages[4]
    Tabelle = Seite.extract_table()
    print(Tabelle)

current output:

Tabelle = [
['Inhaltsstoff', 'CAS-Nr.', 'Wert', '', 'Zu', '', 'Grundlage'], 
[None, None, None, None, 'überwachende', None, None], 
[None, None, None, None, 'Parameter', None, None],
... 
]

desired output:

Tabelle = [
['Inhaltsstoff', 'CAS-Nr.', 'Wert', '', 'Zu \nüberwachende \nParameter', '', 'Grundlage'],
... 
]

I don't know which settings in extract_table(table_settings={...}) can lead to my desired output. I would be happy if you could help me.
