title: python scrapy - extract data from <table> - no id tag
body: <p>I'm pretty new to Python and Scrapy that's why I created a project for myself to learn it. But at the moment I'm struggling to get the data from following page: <a href="https://www.immoscout24.ch/en/d/flat-buy-bevilard/4761145?s=2&amp;t=2&amp;l=436&amp;r=40&amp;se=16&amp;ci=3&amp;ct=1290" rel="nofollow noreferrer">Website to crawl</a></p>
  
  <p>As I could see with the "developer tools" from Chrome/Firefox there are 8 tables with the class like this: <code>&lt;table class="sc-fHxwqH ddWfJE"&gt;</code></p>
  
  <p>In this picture <a href="https://i.stack.imgur.com/nIQwR.jpg" rel="nofollow noreferrer">structure and table I'd like to extract</a> you see the structure and the column (<code>&lt;td&gt;</code>) where the value is = "Wheelchair accessible" that I want to extract. The value is in the second column at it is a picture  tag.
  It is to read like this: If I can find it (in this case "Wheelchair accessible"), the value equals true if I can't find it at all, then the value equals false.</p>
  
  <p>I managed things around it like browsing through the parent-detail three of website. But now I can't browse to the correct XPATH to find this table with <code>class="sc-fHxwqH ddWfJE"</code></p>
  
  <p>I tried to narrow it down to the very basics in the shell cmd:</p>
  
  <pre><code>scrapy shell 'https://www.immoscout24.ch/de/d/wohnung-kaufen-bevilard/4761145?s=2&amp;t=2&amp;l=436&amp;r=40&amp;se=16&amp;ci=3&amp;ct=1290'
  tables = response.xpath('//*[@class="sc-fHxwqH ddWfJE"]/table')
  for table in tables[1:]:
      print("I found it!!") #this should be returned 8 times, once for each table
      table.xpath('tr/td[1]//text()').extract_first()
  </code></pre>
  
  <p>The full path to the Wheelchair accessible  is:
  <code>//*[@id="root"]/div/div/div[1]/section/article[7]/table/tbody/tr[1]/td[1]</code></p>
  
  <p>Unfortunately above code doesn't give anything back. I don't get any error, but also no print that I would expect.</p>
  
  <ol>
  <li>What am I doing wrong? I imagine can't be that difficult?</li>
  <li>Once I found the correct table, how would extract the data from the table to a JSON the easiest and fastest way? I imagine this will be quite slow, as basically I need to parse the whole HTML code several times to find if each property-description is there or not?</li>
  </ol>
  
  <p>I appreciate all your help or any tips! I already invested a couple of days trying to figure it out..</p>
