Here's why this works:
* Present Perfect Tense: The present perfect tense describes an action that started in the past and continues to have relevance in the present.
* Lay: The word "lay" is the past tense of "lie" when used to mean "to place something down."
* Have laid: This is the present perfect tense of "lay."
The sentence means that the speaker placed the table setting down, and it is still in place now.
