| 参数1 | 参数2 |
|       | value |

@when('I perform an action without data')
def step_impl(context):
    # Perform action without data
    pass

@then('I should see the result')
def step_impl(context):
    # Check the result
    pass

| 参数1 | 参数2  |
| value | empty |

@when('I perform an action with empty data')
def step_impl(context):
    # Perform action with empty data
    pass

@then('I should see the result')
def step_impl(context):
    # Check the result
    pass

| 参数1     | 参数2         |
| value1    | value2,value3 |

@when('I perform an action with multiple data')
def step_impl(context):
    # Split the multiple data
    data = context.table[0]['参数2'].split(',')
    # Perform action with multiple data
    pass

@then('I should see the result')
def step_impl(context):
    # Check the result
    pass
