Given a table image, please tell me which table cells are merged cells. Return the merged cell regions in the JSON format of {'top-left':(R1, C1), 'bottom-right':(R2, C2)}, where (R1, C1) and (R2, C2) represent the (row_id, column_id) coordinates of top-left cell and bottom-right cell, respectively. The row_id and column_id are numberd from 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(2, 2), 'bottom-right':(2, 4)}
{'top-left':(3, 2), 'bottom-right':(3, 4)}
{'top-left':(7, 2), 'bottom-right':(7, 4)}
{'top-left':(11, 2), 'bottom-right':(11, 4)}
{'top-left':(15, 2), 'bottom-right':(15, 4)}
{'top-left':(19, 2), 'bottom-right':(19, 4)}
{'top-left':(23, 2), 'bottom-right':(23, 4)}
{'top-left':(27, 2), 'bottom-right':(27, 4)}
{'top-left':(31, 2), 'bottom-right':(31, 4)}
{'top-left':(35, 2), 'bottom-right':(35, 4)}
{'top-left':(39, 2), 'bottom-right':(39, 4)}
{'top-left':(43, 2), 'bottom-right':(43, 4)}
{'top-left':(47, 2), 'bottom-right':(47, 4)}.
