Adding ability for Scenario outline table values to be inserted into step tables

In many implementations of Cucumber/Gherkin frameworks it is possible to do something like the following

Scneario Outline: Blah blah
Given something
When I put the following values into the form
| First Name    | Last Name    |
| <first_name> | <last_name> |
Then I expect the submission to be <success_or_fail>

Examples:
| first_name | last_name | success_or_fail |
| Foo          | Bar           | Successful       |
| Foo          |                 | Unsuccessful   |
