Title: NoMethodError: undefined method `cell_matrix' for [...]:Cucumber::MultilineArgument::DataTable

I've played with test for http://youtrack.jetbrains.com/issue/RUBY-11291 and found that it raises exception with 2.0.0.beta.2
NoMethodError: undefined method `cell_matrix' for [{"type"=>"pending", "key"=>"FO-1"}]:Cucumber::MultilineArgument::DataTable
./features/step_definitions/ruby-11291.rb:5:in `/^this table crashes:$/'
/Users/user/work/tests/cucumber-tests/features/ruby-11291.feature:3:in `Then this table crashes:'

I'm not sure if calling `#diff!` is still supported thus I've decided to file a ticket to discuss this.
