Not all variants of empty examples tables are parsed in same way

[elchupanebrej]

When I execute any of next 3 scenarios they are passing(OK)

Feature: Outline
    Scenario Outline: Outlined given, when, thens
        Given there are 12 apples
        When I eat 5 apples
        Then I should have 7 apples

        Examples:

Feature: Outline
    Scenario Outline: Outlined given, when, thens
        Given there are 12 apples
        When I eat 5 apples
        Then I should have 7 apples

        Examples: Vertical

Feature: Outline
    Scenario Outline: Outlined given, when, thens
        Given there are 12 apples
        When I eat 5 apples
        Then I should have 7 apples
        Examples:

But when I execute the next scenario - it fails (not OK):

Feature: Outline
    Scenario Outline: Outlined given, when, thens
        Given there are 12 apples
        When I eat 5 apples
        Then I should have 7 apples

        Examples: Vertical
        |

with error:

Pay attention that the next variant is used by Cucumber.io by default for empty tables

This fixed by #478

Vertical tables are going to be deprecated.
