我试着从一个网站上抓取一个表格，但是我一直得到一个IndexError，不能前进

import requests
from bs4 import BeautifulSoup

url = 'http://example.com/page-with-table'
response = requests.get(url)
soup = BeautifulSoup(response.content, 'html.parser')

# 假设表格的id是'my-table'
table = soup.find('table', id='my-table')
if table:
    rows = table.find_all('tr')
    for i, row in enumerate(rows):
        try:
            # 假设每行有三个单元格
            cells = row.find_all('td')
            if len(cells) >= 3:
                cell1 = cells[0].text.strip()
                cell2 = cells[1].text.strip()
                cell3 = cells[2].text.strip()
                print(f"Row {i}: {cell1}, {cell2}, {cell3}")
            else:
                print(f"Row {i} has fewer than 3 cells")
        except IndexError as e:
            print(f"Error processing row {i}: {e}")
else:
    print("Table not found")
