BUtils for Sheets
OpenDevEd has been streamling our Google Docs / Sheets / Slides workflows for many years, going back almost until the initial launch of apps script. For more details about all our Add-ons, see Our Tools.
BUtils for Sheets provides a number of utility functions for Google Sheets. In particular, it offers a default style, as well as cropping of rows/cols that are not needed.
