In this table image, are there any merged cells? If so, describe their locations using the JSON format {'top-left':(R1, C1), 'bottom-right':(R2, C2)}, where (R1, C1) and (R2, C2) indicate the (row_id, column_id) of top-left and bottom-right cells in the merged regions, respectively. Note that the R1, C1, R2, C2 all start from 1.

The merged cell regions 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, 5)}
{'top-left':(1, 6), 'bottom-right':(1, 7)}
{'top-left':(1, 8), 'bottom-right':(1, 9)}
{'top-left':(1, 10), 'bottom-right':(2, 10)}
{'top-left':(4, 1), 'bottom-right':(5, 1)}.
