Given a table image, please tell me which table cells are merged cells. Return the merged cell areas in the JSON format of {'top-left':(A, B), 'bottom-right':(C, D)}, where (A, B) and (C, D) 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 areas are as follows:
{'top-left':(1, 1), 'bottom-right':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 5)}
{'top-left':(2, 2), 'bottom-right':(3, 2)}
{'top-left':(2, 3), 'bottom-right':(3, 3)}
{'top-left':(2, 4), 'bottom-right':(2, 5)}
{'top-left':(5, 2), 'bottom-right':(5, 5)}
{'top-left':(12, 2), 'bottom-right':(12, 5)}
{'top-left':(15, 2), 'bottom-right':(15, 5)}
{'top-left':(19, 2), 'bottom-right':(19, 5)}
{'top-left':(24, 2), 'bottom-right':(24, 5)}
{'top-left':(38, 2), 'bottom-right':(38, 5)}
