Union operator between tables

Hi everyone

I need to merge the data from two omogenous tables (be aware: two tables not two data services; the tables are populated by the user). I specifically need to do this client-side.

When I try to connect the out port of a table to the union operator, the input ports of the operator are grayed out.

I assume the union operator can be used only to merge data from data services: has anyone faced this issue before?

Thanks
