Python 运行时错误：未指定表列/单元格宽度，无法继续

我正试图在PythonDjango中使用pyfpdf创建一个PDF文件。下面的代码片段我正在尝试生成pdf格式的html代码

    from fpdf import FPDF, HTMLMixin
    class WriteHtmlPDF(FPDF, HTMLMixin):
        pass

    html = f"""<h3>xxxxx</h3>
 <div style="border:1px solid #000">
     <table border="1" cellpadding="5" cellspacing="0" width="100%">
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxx</td></tr>
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxxx</td></tr>
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxxx</td></tr>
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxxx</td></tr>
     </table>
 </div>
 <div>
     <table border="1" cellpadding="5" cellspacing="0" align="center" width=100>
         <tr>
             <td width=33>xxxxxx: 1</td>
             <td width=33>xxxxxx: 0</td>
             <td width=33>xxxxxx: 1</td>
         </tr>
     </table>

    pdf.add_page()
    pdf.write_html(html)
    pdf.output('html.pdf', 'F')

我尝试了解决方案，但仍然得到相同的错误

看起来

writehtmlpf（）

不喜欢

和

标记

一个小小的抽搐修正：

from fpdf import FPDF, HTMLMixin
import os

class WriteHtmlPDF(FPDF, HTMLMixin):
    pass

pdf = WriteHtmlPDF()
# First page
pdf.add_page()

html = f"""<h3>xxxxx</h3>
