python docx通过关键字标注字体以及颜色大小等

主要使用python-docx 与pandas

因为python-docx对表格的解析不够友好且效率低，故需转换一次

代码如下

# coding:utf-8
import os, re
import docx
from docx.document import Document as dc
from docx.oxml.table import CT_Tbl
from docx.oxml.text.paragraph import CT_P
from docx.table import _Cell, Table
from docx.text.paragraph import Paragraph
from docx.shared import RGBColor  # 设置字体颜色
from docx import Document
from docx.shared import Pt  # 设置字体
from docx.oxml.ns import qn  # 设置中文字体
import pandas as pd

FILE_PATH = r"D:\xxxx\xxxx\xxxx\xxxx.docx"

obj = docx.Document(FILE_PATH)
