wkhtmltopdf 转换后 表格不显示

   def post(self, request, *args, **kwargs):
		
        # 获取的直接是富文本中的html字符串
        content = request.DATA.get('content')

        file_name = request.DATA.get('file_name')

        file_type = request.DATA.get('file_type')

        direction = request.DATA.get('direction')

        options = constants.PDFKIT_OPTIONS
		
        # 横向 或 纵向
        if direction:
            options['orientation'] = 'Landscape'
		
        # 判断如果有table 加上样式，就可以显示表格了
        if '<table' in content:
            content = '<style>table {max-width: 100%;} td {border: 1px solid #ccc;}</style>' + content

        file_path = '{}_{}.pdf'.format(file_name, uuid.uuid4())
        ExportPdfHelper(content, file_path, options).export_pdf()

	这里实际调用pdfkit.from_string方法，
        pdfkit.from_string(self.content, self.file_path, configuration=self.config, options=self.options)
        
        参数：
	content：h5字符串 
	file_path：生成的pdf存放位置,
        configuration: pdfkit.configuration(wkhtmltopdf=settings.WKHTMLTOPDF_PATH) 工具位置
        options：
        PDFKIT_OPTIONS = {
            'page-size': 'Letter',
            'margin-top': '0.75in',
            'margin-right': '0.75in',
            'margin-bottom': '0.75in',
            'margin-left': '0.75in',
            'encoding': "UTF-8",
            'no-outline': None,
            'quiet': '',
            'enable-forms': '',
        }
        options 明细 https://www.jianshu.com/p/4d65857ffe5e

        ret, info = upload_file_to_qiniu(file_path, file_path)

        qiniu_url = settings.QINIU_CDN_DOMAIN + "/" + ret['key']

        return Response({'status': 1, 'file_url': qiniu_url})


# 如果不想表格被分页打断, border防止表格线变双行
'<style>' \
         'table {max-width: 100%;  ' border-collapse: collapse;} ' \
         ' td {border: 1px solid #ccc;}' \
          'table {page-break-inside: avoid !important;}' \
