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 IDs begin from 1.
Refer to the values below:
1. 'Erica',
2. '12',
3. 'Name',

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

The target cell locations are as follows:
1. {'value': 'Erica', 'location': (3, 1)}
2. {'value': '12', 'location': (4, 2)}
3. {'value': 'Name', 'location': (2, 1)}
