Join
Client::join creates a read-only Table by joining two source tables on a
shared key column. The left and right arguments can be Table objects or
string table names (as returned by get_hosted_table_names()). The resulting
table is reactive: whenever either source table is updated, the join is
automatically recomputed and any View derived from the joined table will
update accordingly.
Joined tables support the full View API — you can apply group_by,
split_by, sort, filter, expressions, and all other View operations on
the result, just as you would with any other Table.
