What symbol is used for parameterization in Cucumber?

Scenario Outline: Login with <role>
  When the user enters "<username>" and "<password>"
  Then the user sees the "<dashboard>"

  Examples:
    | role    | username | password  | dashboard |
    | admin   | admin    | Admin@123 | AdminHome |
    | manager | manager  | Mgr@456   | MgrHome   |

  Examples:
    | filename |
    | file1    |
    | file2    |

  When the user submits the registration form:
    | Field     | Value            |
    | FirstName | John             |
    | LastName  | Doe              |
    | Email     | john@example.com |
    | Mobile    | 9876543210       |

// Scenario Outline parameters passed as method arguments
@When("the user enters {string} and {string}")
public void enterCredentials(String username, String password) {
    // username, password come from Examples table row
}

// Data Table accessed via DataTable object
@When("the user submits the registration form:")
public void submitForm(DataTable dataTable) {
    Map<String, String> formData = dataTable.asMap(String.class, String.class);
    String firstName = formData.get("FirstName");
    String email = formData.get("Email");
}

{string}    // matches "quoted string"
{int}       // matches integer: 42
{float}     // matches decimal: 3.14
{word}      // matches single word (no spaces)
{}          // matches anything (anonymous)
