How to reuse Cucumber step definition with a table for the last parameter?

Question

This code:

Then %{I should see the following data in the "Feeds" data grid:
                                                   |   Name   |
                                                   | #{name}  |}

And this one:

Then "I should see the following data in the \"Feeds\" data grid:
|   Name   |
| #{name}  |"

And this:

  Then "I should see the following data in the \"Feeds\" data grid:\n|   Name   |\n| #{name}  |"

And even this:

Then <<EOS
I should see the following data in the "Feeds" data grid:
|   Name   |
| #{name}  |
EOS

Gives me:

Your block takes 2 arguments, but the Regexp matched 1 argument.

This one:

Then "I should see the following data in the \"Feeds\" data grid: |   Name   || #{name}  |"

And this one:

Then "I should see the following data in the \"Feeds\" data grid:|   Name   || #{name}  |"

Gives:

Undefined step: "I should see the following data in the "Feeds" data grid:|   Name   || myFeed  |" (Cucumber::Undefined)

Answer 1

I've found the answer myself:

steps %Q{
Then I should see the following data in the "Feeds" data grid:
                                                |   Name   |
                                                | #{name}  |
}
