如何格式化"rake路线"？

我想做一个rake任务,以markdown风格输出路线.

|  Prefix Verb   |        URI Pattern        | Controller#Action |
| -------------- | ------------------------- | ----------------- |
|     users GET  | /users(.:format)          | users#index       |
|           POST | /users(.:format)          | users#create      |
|  new_user GET  | /users/new(.:format)      | users#new         |
| edit_user GET  | /users/:id/edit(.:format) | users#edit        |
|      user GET  | /users/:id(.:format)      | users#show        |

有没有办法在Rails4中实现这一目标？
