Dinner was laid out on the table.
Literal
Dinner [subject-が] table [on-に] arrange-[passive-past-られた].
並べる ('to arrange, line up, set out') is transitive; the passive 並べられた is 'was arranged [by someone].' Using passive voice for the setting of a table is common in written Japanese to focus on the scene rather than the person doing the work — 'dinner was laid out,' without specifying who laid it out.
