Given a table image and a set of target cells, your task is to identify their positions. Represent each cell's location as JSON in the format {'value': '<cell value>', 'location': (row_id, column_id)}, with both row and column id begin from 1.
Refer to the values below:
(1) 'Yo-yos',
(2) '950',
(3) 'Model airplanes',

Denote the location as 'DOES NOT EXIST' if a cell does not exist in the table. 

The coordinates of target cells are listed below.
(1) {'value': 'Yo-yos', 'location': (5, 1)}
(2) {'value': '950', 'location': (5, 2)}
(3) {'value': 'Model airplanes', 'location': (3, 1)}
