Creating hashes from parsed HTML

Creating hashes from parsed HTML

I'm getting second table from this page, parse it and trying to generate
hashes from this data. The problem is that each object is separated by
this grey TR but I can only manage this by getting every single TR from
this table.
How can I determine proper TR by getting those between gray ones?
For now I'm using this line to get each TR:
parsed_html.css("table")[1].css("tr")
