In regards to new bench for hire (8)

I believe the answer is:

rentable

I'm a little stuck... Click here to teach me more about this clue!

'in regards to new' is the definition.
I can't tell whether this definition defines the answer.

'bench for hire' is the wordplay.
'bench' becomes 'table' (I've seen this in other clues).
'for' says to put letters next to each other (I've seen this in other clues).
'hire' becomes 'ren' (I can't explain this - if you can you should believe this answer much more).
'table' after 'ren' is 'RENTABLE'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
