What type of PR is this?

• [x] Feature

Description

It would be better if the "Created By" column on the query list page were also sortable. This would allow users to quickly locate queries by the author's name. Our support engineers have found this feature particularly helpful.

How is this tested?

• [x] Manually

Created By is sortable with proper icons/headshots and width
