Table:
Number spun	Frequency

1	2

2	14

3	15

4	12

5	3

6	6

Examine the given table and locate the cells that contain the following values:
(1) '14',
(2) '15',
(3) '1',
(4) '4',
(5) 'Number spun',
(6) 'Frequency',
(7) '12',
(8) '5',
Return the cell locations using the JSON format {'value': '<cell value>', 'location': (row_id, column_id)}, where both row and column id commence from 1. For the case where a cell is not contained in the table, its location should be denoted as 'DOES NOT EXIST'.

The target cell locations are as follows:
(1) {'value': '14', 'location': (4, 2)}
(2) {'value': '15', 'location': (5, 2)}
(3) {'value': '1', 'location': (3, 1)}
(4) {'value': '4', 'location': (6, 1)}
(5) {'value': 'Number spun', 'location': (2, 1)}
(6) {'value': 'Frequency', 'location': (2, 2)}
(7) {'value': '12', 'location': (6, 2)}
(8) {'value': '5', 'location': (7, 1)}
