Return the merged cell areas in the provided table image. Your answer should be in the JSON format of {'top-left':(x, y), 'bottom-right':(m, n)}, where (x, y) and (m, n) represent the (row_id, column_id) coordinates of top-left cell and bottom-right cell, respectively. Note that row_id and column_id start from 1 instead of 0.

The merged cell areas are as follows:
{'top-left':(1, 1), 'bottom-right':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 4)}
{'top-left':(1, 5), 'bottom-right':(1, 7)}
{'top-left':(3, 2), 'bottom-right':(3, 7)}
{'top-left':(4, 2), 'bottom-right':(4, 7)}
{'top-left':(8, 2), 'bottom-right':(8, 7)}.
