A table may have multiple cells. We can utilize the json format {'value': '<cell value>', 'location': (Row_ID, Column_ID)} to store a cell's positions in a table, where both row and column IDs start from 1. I am providing you a table image. Please tell me the positions of the cells mentioned below using the above format. Represent the location as 'DOES NOT EXIST' if a cell is not present in the table.
Values to locate:
CELL VALUE 1: '148'
CELL VALUE 2: 'percentage'
CELL VALUE 3: 'mean number of hours'

The target cell locations are as follows:
CELL LOCATION 1: {'value': '148', 'location': (6, 3)}
CELL LOCATION 2: {'value': 'percentage', 'location': (1, 2)}
CELL LOCATION 3: {'value': 'mean number of hours', 'location': (1, 3)}
