、。
Mother cleared the table.
Literal
Mother, [topic-は] dining-table [gen-の] things [obj-を] cleared.
The comma after 母 is unusual — most modern Japanese wouldn't set a topic off from は this way. This is probably a quirk of the original source or a reading-aid for a reader meant to pause. 片付ける ('tidy up, put away, clear') is broad — it covers cleaning tables, tidying rooms, settling matters.
