Examples of pages where this functionality would be helpful
editCoaches and players of many sports
editNote this is one example of thousands of articles about coaches and players in multiple sports, where table of accomplishments exist, and need updating as time progress.
List of fires
editNote that one table does have averages, which would be easier to update is math in tables existed. However, two other tables exist in that article, both of whom might be better if totals and/or averages were included. Presumably not included because of the pain of updating.
Hurricane damage tables
editMany Hurricane pages do not have a damage table, but some do. Not a major need when the data is old, but could be useful while values are being updated.
