About Merging

Join: Creates a JoinedTable that combines columns from multiple tables (similar to a SQL JOIN on row index). Both tables must have the same number of rows.

Union: Concatenates rows from multiple tables that share the same schema. (Coming soon)

Merged tables maintain full revision history and can be viewed in the DAG view.
