。
She poured coffee into the cup on the table.
Literal
She [topic-は] table [genitive-の] top [genitive-の] cup [into-に] coffee [object-を] poured.
Two stacked の particles build the noun phrase: テーブルの上 ('the top of the table') and then の cup ('a cup') — 'a cup on top of the table.' The に on the cup marks it as the destination of the pouring; 注ぐ takes に for the receiver of the liquid. The chained の structure is a backbone of Japanese noun-phrase building: each の adds another layer of attribution, and the head noun comes last.
