In this table image, are there any merged cells? If so, describe their locations using the JSON format {'top-left':(x, y), 'bottom-right':(m, n)}, where (x, y) and (m, n) indicate the (row_id, column_id) of top-left and bottom-right cells in the merged regions, respectively. Note that the x, y, m, n all start from 1.

The merged cell areas are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(1, 2), 'bottom-right':(2, 2)}
{'top-left':(1, 3), 'bottom-right':(1, 4)}
{'top-left':(1, 5), 'bottom-right':(1, 6)}
{'top-left':(1, 7), 'bottom-right':(1, 8)}
{'top-left':(1, 9), 'bottom-right':(1, 10)}
{'top-left':(1, 11), 'bottom-right':(2, 11)}
