In this table image, are there any merged cells? If so, describe their locations using the JSON format {'top-left':(X1, Y1), 'bottom-right':(X2, Y2)}, where (X1, Y1) and (X2, Y2) indicate the (row_id, column_id) of top-left and bottom-right cells in the merged regions, respectively. Note that the X1, Y1, X2, Y2 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':(2, 2)}
{'top-left':(1, 3), 'bottom-right':(1, 5)}
{'top-left':(1, 6), 'bottom-right':(1, 8)}
{'top-left':(3, 2), 'bottom-right':(3, 8)}
{'top-left':(5, 2), 'bottom-right':(5, 8)}
{'top-left':(6, 2), 'bottom-right':(6, 8)}.
