how to show page number of difference in pdf text comparison html table?

Question

This HTML table comparing two novels notes the detected differences with the 'n' but also lists the word count; instead, I would like it to list the page number from the two documents where this difference occurs.

import textract
import difflib
import nltk
import re[![enter image description here][1]][1]
text = textract.process('scarletfirsted.pdf', method = 'tesseract')
book1 = text.decode()
text = textract.process('scarletsecond.pdf', method = 'tesseract')
book2 = text.decode()
from nltk.tokenize import sent_tokenize, word_tokenize
from IPython.core.display import HTML
words1 = nltk.word_tokenize(book1)
words2 = nltk.word_tokenize(book2)
htmldiff = difflib.HtmlDiff()
tbl = htmldiff.make_table(words1, words2, context = True)
HTML(tbl)
