I am trying to populate a Lightning Web Component that I put together with particular Case fields. No matter what I try, I can't get any data into my Lightning-DataTable. Does anyone know how to do this?
Its Not possible.
Lightning data service is meant to work on single record and you need
List of records in data-table. Although we get the property
records (which is single record) in data-service, there is nothing in roadmap as of now which shows data-service will be made to get list of records.
As of today, you should get the list of records from Apex only.
