Cucumber table diff for partial rows

gistfile1.rb

Then /^the table should contain the following rows:$/ do |table|
  table_element = find('table.standard')
  headers = table_element.all('thead th').map(&:text)
  result = table_element.all('tbody tr').map do |tr|
    {}.tap do |hash|
      tds = tr.all('td').map(&:text)
      headers.each_with_index do |header, i|
        hash[header] = tds[i]
      end
    end
  end
  table.diff!(result, surplus_row: false)
end

parsing a table is even easier than that. You don't have to fold the rows into hashes yourself, the table method will do that for you. https://github.com/hashrocket/tms/blob/master/features/support/table.rb#L8

good to know, the code becomes clearer
