Increase width of table column


We have decided (for reasons I won’t get into here) to use a table in each command description to document our API parameter details.

What I’m wondering is - is there a way for me to improve the styling of this table at all? Specifically, I would like to increase the width of some columns (like the Range one that is quite squashed in the screenshot above).

Is there any way to edit the width of table columns in line? Or via CSS somehow?

I do not have much experience with HTML, CSS, or Postman so any help would be greatly appreciated.
