Union of examples tables is broken #479
Description
When I execute Feature
Feature: Outline
Scenario Outline: Outlined given, when, thens
Given there are <start> cucumbers
When I eat <eat> cucumbers
Then I should have <left> cucumbers
Examples:
| start | eat | left |
| 12 | 5 | 7 | # a comment
Examples:
| start | eat | left |
| 5 | 4 | 1 | # a commentTwo scenarios are executed (OK)
But when I execute Feature:
Feature: Outline
Scenario Outline: Outlined given, when, thens
Given there are <start> cucumbers
When I eat <eat> cucumbers
Then I should have <left> cucumbers
Examples:
| start | eat | left |
| 12 | 5 | 7 | # a comment
Examples: Vertical
| start | 5 |
| eat | 4 |
| left | 1 |The test fails with (not OK):
