I have a lightning datatable which is having various no. of columns.
Problem is that User has to scroll to right end to find the vertical scrollbar, I want the vertical scroller to be on the screen always so that whenver user wants to scroll down he can do it through scroller.
Please suggest any ideas how to achieve this.

Tried doing a callout from an execute method in a queueable class and go the @future error -

Callout not allowed from this future method. Please enable callout by annotating the future method. eg: @Future(callout=true)
07:13:51.752 (8701449752265601)|SYSTEM_METHOD_EXIT|[1263]|System.Http.send(ANY)

Is there a way to annotate the execute with "(callout=true)".

I sounds like what i want to do may be doable if there's just some syntax to get the annotation.
