To complete your task, analyze the table image and identify the positions of the specified cells. Ensure that you represent a cell's location using the JSON format {'value': '<cell value>', 'location': (row index, column index)}, with both row and column indices starting from 1. Use 'DOES NOT EXIST' as the location for a non-existing cell in the table.
Target cells:
1. 'cosmetic treatments',
2. '59.1',
3. '11.7',
4. 'pointer',

The coordinates of target cells are listed below.
1. {'value': 'cosmetic treatments', 'location': (20, 1)}
2. {'value': '59.1', 'location': (11, 2)}
3. {'value': '11.7', 'location': (19, 3)}
4. {'value': 'pointer', 'location': (19, 1)}
