python-docx 判断表格的边框是实线还是无边框

import os
import docx

from docx.document import Document
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.oxml.ns import nsmap

import pandas as pd
import re
from lxml import etree
from docx.oxml.ns import qn

def has_table_borders(table:Table):
    #获取表格的tblPr
    tblPr = table._element.find('w:tblPr', namespaces=nsmap)
    tblBorders = tblPr.find('w:tblBorders', namespaces=nsmap)
    #获取所有boarder的val
    border_val_list=[border.get(qn('w:val')) for border in tblBorders]
    #如果所有boarder的val中不全为"none"或不全为"nil"，则返回True
    if border_val_list.count('none')+border_val_list.count('nil')!=len(border_val_list):
        return True #表格有边框

    return False #表格无边框

border有以下几种属性：color、shadow、space、sz、val。通过val属性可以判断边框是实线、虚线还是无边框。关于这几种属性的详细信息可以参考这篇博客
