Fails when using multiline argument tables with scenario outlines

[saclark]

PrettyFace appears to be failing when using multiline argument tables in conjunction with scenario outlines. For example:

Scenario Outline: Example
    Given the following data
        | Foo        | Bar        |
        | <foo_data> | <bar_data> |
    Then things should work

    Examples:
        | foo_data  | bar_data  |
        | abcd      | 1234      |

The above scenario outline causes PrettyFace to fail with the following message:

undefined method `table=' for #<Cucumber::Ast::Step:0x42fab48> (NoMethodError)

which comes from:

lib/pretty_face/formatter/html.rb:120:in `after_step'

Woops! Just saw that this is a duplicate of issue #19. Closing this. Thanks.
