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) '86.9',
(2) '1,745',
(3) '45',
(4) '84.2',
(5) '86.5',
(6) '2,070',
(7) '300',
(8) '25',
(9) '17,440',

Some cell values may not be contained in this table. If so, represent their locations as 'DOES NOT EXIST'. 

The target cell locations are as follows:
(1) {'value': '86.9', 'location': (12, 4)}
(2) {'value': '1,745', 'location': (10, 3)}
(3) {'value': '45', 'location': (13, 2)}
(4) {'value': '84.2', 'location': (10, 4)}
(5) {'value': '86.5', 'location': (4, 4)}
(6) {'value': '2,070', 'location': (10, 2)}
(7) {'value': '300', 'location': (5, 2)}
(8) {'value': '25', 'location': (15, 2)}
(9) {'value': '17,440', 'location': (8, 3)}
