我正在尝试使用一系列PDF图像和一系列CSV表格创建一个PDF文档，这些表格给了我一点悲伤。
这是我的代码：

import os
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate
from reportlab.pdfgen.canvas import Canvas
from reportlab.platypus import *
from reportlab.platypus.tables import Table
from PIL import Image
from matplotlib.backends.backend_pdf import PdfPages

# Set the path to the folder containing the images and tables
folder_path = 'Files'

# Create a new PDF document
pdf_filename = 'testassessment.pdf'
canvas = Canvas(pdf_filename)

# Iterate through the files in the folder
for file in os.listdir(folder_path):
  file_path = os.path.join(folder_path, file)
  
  # If the file is an image, draw it on the PDF
  if file.endswith('.png'):
    canvas.drawImage(file_path, 105, 148.5, width=450, height=400) 
    canvas.showPage() #ends page
    
  # If the file is a table, draw it on the PDF
  elif file.endswith('.csv'):
    df = pd.read_csv(file_path)
    table = df.to_html()
    canvas.drawString(10, 10, table)
    canvas.showPage() 
    
# Save the PDF
canvas.save()

表不工作。当我使用. drawString时，它最终看起来像这样：

有人知道我如何才能把表格正确地插入到PDF中吗？
