Examine the table in this image and extract any merged cell areas. Please format the merged cell areas as JSON {'top-left':(A, B), 'bottom-right':(C, D)}, with (A, B) indicating the (row_id, column_id) of the top-left cell and (C, D) the bottom-right cell in the merged regions. Remember that the A, B, C, D all start from 1.

The merged cell areas are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(2, 2), 'bottom-right':(2, 9)}
{'top-left':(3, 2), 'bottom-right':(3, 9)}
{'top-left':(11, 2), 'bottom-right':(11, 9)}.
