将csv作为表格导入docx时，如何将列标题与每列中的值对齐？

import csv
from docx import Document
from docx.enum.table import WD_ALIGN_VERTICAL, WD_ALIGN_VERTICAL
from docx.shared import Pt

def import_csv_to_docx(csv_file, docx_file):
    # 读取csv文件
    with open(csv_file, 'r') as file:
        csv_data = list(csv.reader(file))

    # 创建docx文档对象
    doc = Document()

    # 添加一个表格
    table = doc.add_table(rows=1, cols=len(csv_data[0]))

    # 设置表格样式
    table.style = 'Table Grid'

    # 设置列标题
    for i, header in enumerate(csv_data[0]):
        cell = table.cell(0, i)
        cell.text = header
        cell.paragraphs[0].alignment = WD_ALIGN_PARAGRAPH.CENTER
        cell.vertical_alignment = WD_ALIGN_VERTICAL.CENTER
        cell.paragraphs[0].runs[0].bold = True
        cell.paragraphs[0].runs[0].font.size = Pt(12)

    # 添加每列的值
    for row in csv_data[1:]:
        table.add_row()
        for i, value in enumerate(row):
            cell = table.cell(len(table.rows)-1, i)
            cell.text = value
            cell.paragraphs[0].alignment = WD_ALIGN_PARAGRAPH.CENTER
            cell.vertical_alignment = WD_ALIGN_VERTICAL.CENTER
            cell.paragraphs[0].runs[0].font.size = Pt(12)

    # 保存docx文件
    doc.save(docx_file)

# 调用函数导入csv到docx
import_csv_to_docx('data.csv', 'output.docx')
