"That's that" is an idiomatic expression used to indicate that a particular situation or matter is finished or concluded. It is often used to signal that there is nothing further to be said or done about a particular topic. For example, if you have just finished a project at work and someone asks if there is anything else you need to work on, you might say "No, that's that." Alternatively, if you have had a disagreement with someone and have come to an agreement, you might say "Well, that's that then." Essentially, "that's that" is a way of saying "we are finished with this matter" or "there is nothing further to be said or done."
