title: can not find table content (hidden table) when scrapy on a web
body: <p>I am trying to scrape the following url (<a href="http://cmegroup.com/clearing/operations-and-deliveries/accepted-trade-types/block-data.html/#contractTypes=FUT&amp;exchanges=XNYM&amp;assetClassId=0" rel="nofollow noreferrer">http://cmegroup.com/clearing/operations-and-deliveries/accepted-trade-types/block-data.html/#contractTypes=FUT&amp;exchanges=XNYM&amp;assetClassId=0</a>), the table content is what I'm interested, however looks like the table is hidden at somewhere:</p>
  
  <p>Right click the inspection on the table, I can get  ==$0 (following by )
  But at scrapy shell, if I do response.xpath('//*[@table]'), it returns nothing which means I can't scrape the content by this way....
  Please help on this issue, thanks.</p>
  
  <p>UPDATE: The final solution is by using Selenium (great tool) for this scrapy task, and selenium is especially useful when the web page content such as tables and etc. is java encrypted, there are tons of selenium instruction to be found in the community, here is one <a href="https://stackoverflow.com/questions/13724778/how-to-run-selenium-webdriver-test-cases-in-chrome">example</a>.</p>
