Table:
Stem	Leaf

1	2, 4, 4, 7, 8, 8, 9

2	1, 4, 6, 7

3	3, 4, 4, 7

4	1, 2, 4, 8, 8

In this task, you are provided with a table image and several target cells. You are required to determine the positions of these cells, which can be represented in the json {'value': '<cell value>', 'location': (row index, column index)}, with both row indices and column indices start from 1. Some cell values may not be contained in this table. If so, represent their locations as 'DOES NOT EXIST'.
Cell values are shown below:
1. 'Stem',
2. '3, 4, 4, 7',
3. '4',
4. 'Central American Championships',
5. '2, 4, 4, 7, 8, 8, 9',
6. '2007',
7. 'Santo Domingo, Dominican Republic',

The coordinates of target cells are listed below.
1. {'value': 'Stem', 'location': (2, 1)}
2. {'value': '3, 4, 4, 7', 'location': (5, 2)}
3. {'value': '4', 'location': (6, 1)}
4. {'value': 'Central American Championships', 'location': 'DOES NOT EXIST'}
5. {'value': '2, 4, 4, 7, 8, 8, 9', 'location': (3, 2)}
6. {'value': '2007', 'location': 'DOES NOT EXIST'}
7. {'value': 'Santo Domingo, Dominican Republic', 'location': 'DOES NOT EXIST'}
