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

The merged cell areas are as follows:
{'top-left':(1, 1), 'bottom-right':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 3)}
{'top-left':(1, 4), 'bottom-right':(1, 5)}
{'top-left':(5, 2), 'bottom-right':(5, 5)}
{'top-left':(11, 2), 'bottom-right':(11, 5)}
{'top-left':(17, 2), 'bottom-right':(17, 5)}
{'top-left':(23, 2), 'bottom-right':(23, 5)}
{'top-left':(36, 2), 'bottom-right':(36, 5)}
{'top-left':(41, 2), 'bottom-right':(41, 5)}.
