### _Why are the changes needed?_
When the get server and list server commands are displayed, when the namespace exceeds the minimum width, it will be glued to the hostname.

- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [x] Add screenshots for manual tests if appropriate
