Return the merged cell areas in the provided table image. Your answer should be 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. 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':(1, 8), 'bottom-right':(1, 10)}
{'top-left':(1, 11), 'bottom-right':(1, 13)}
{'top-left':(1, 14), 'bottom-right':(1, 16)}
{'top-left':(2, 2), 'bottom-right':(3, 2)}
{'top-left':(2, 3), 'bottom-right':(2, 4)}
{'top-left':(2, 5), 'bottom-right':(3, 5)}
{'top-left':(2, 6), 'bottom-right':(2, 7)}
{'top-left':(2, 8), 'bottom-right':(3, 8)}
{'top-left':(2, 9), 'bottom-right':(2, 10)}
{'top-left':(2, 11), 'bottom-right':(3, 11)}
{'top-left':(2, 12), 'bottom-right':(2, 13)}
{'top-left':(2, 14), 'bottom-right':(3, 14)}
{'top-left':(2, 15), 'bottom-right':(2, 16)}
{'top-left':(7, 2), 'bottom-right':(7, 16)}.
