Table:
Number of baskets	Number of flowers

1	10

2	20

3	30

4	?

To fulfill your task, review the table image and pinpoint the positions of the specified cells. Make sure to represent a cell's location using the JSON format {'value': '<cell value>', 'location': (Row_ID, Column_ID)} which begin from '(1, 1)'.
Target cells:
(1) '4'
(2) '1'
(3) '?'
(4) '20'
(5) '3'
(6) '10'
(7) '2'

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': '4', 'location': (5, 1)}
(2) {'value': '1', 'location': (2, 1)}
(3) {'value': '?', 'location': (5, 2)}
(4) {'value': '20', 'location': (3, 2)}
(5) {'value': '3', 'location': (4, 1)}
(6) {'value': '10', 'location': (2, 2)}
(7) {'value': '2', 'location': (3, 1)}
