python之Pandas read_html 导致 TypeError

我正在使用 bs4 解析一个 html 页面并提取一个表，下面给出了示例表，我试图将它加载到 pandas 中，但是当我调用 pddataframe = pd.read_html(LOTable,skiprows=2 , flavor=['bs4']) 我得到下面列出的错误，但我可以打印由 bs4 美化的表格

有什么建议可以解决这个问题而无需获取每个 td 并逐一读取吗？

示例表

<table cellpadding="5" cellspacing="0" class="borders" width="100%"> 
    <tr> 
     <th colspan="2"> 
      Learning Outcomes 
     </th> 
    </tr> 
    <tr> 
     <td class="info" colspan="2"> 
      On successful completion of this module the learner will be able to: 
     </td> 
    </tr> 
    <tr> 
     <td style="width:10%;"> 
      LO1 
     </td> 
     <td> 
      Demonstrate an awareness of the important role of Financial Accounting information as an input into the decision making process. 
     </td> 
    </tr> 
    <tr> 
     <td style="width:10%;"> 
      LO2 
     </td> 
     <td> 
      Display an understanding of the fundamental accounting concepts, principles and conventions that underpin the preparation of Financial statements. 
     </td> 
    </tr> 
    <tr> 
     <td style="width:10%;"> 
      LO3 
     </td> 
     <td> 
      Understand the various formats in which  information in relation to transactions or events is recorded and classified. 
     </td> 
    </tr> 
    <tr> 
     <td style="width:10%;"> 
      LO4 
     </td> 
     <td> 
      Apply a knowledge of accounting concepts,conventions and techniques such as double entry to the  posting of  recorded information to the T accounts in the Nominal Ledger. 
     </td> 
    </tr> 
    <tr> 
     <td style="width:10%;"> 
      LO5 
     </td> 
     <td> 
      Prepare and present the financial statements of a Sole Trader  in prescribed format from a Trial Balance  accompanies by notes with additional information. 
     </td> 
    </tr> 
   </table>

请您参考如下方法:

感谢所有建议的答案和评论中的指点，我的菜鸟错误是我在使用 bs4 提取表格后将其放在变量中。 我正在运行 pd.read_html(LOTable,skiprows=2, flavor='bs4') 当我需要运行 pd.read_html(LOTable.pretify(),skiprows=2, flavor= 'bs4')
