The task is as follows:
Analyze the table in this image to find every merged cell. Return the regions of these merged cells in the JSON {'top-left':(A, B), 'bottom-right':(C, D)}, where '(A, B)' and '(C, D)' show the (row_id, column_id) of the top-left and bottom-right cells in these regions, respectively. The row and column IDs start from 1.

The merged cell regions 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':(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':(4, 2), 'bottom-right':(4, 7)}
{'top-left':(9, 2), 'bottom-right':(9, 7)}
{'top-left':(12, 2), 'bottom-right':(12, 7)}
{'top-left':(15, 2), 'bottom-right':(15, 7)}
{'top-left':(18, 2), 'bottom-right':(18, 7)}
{'top-left':(21, 2), 'bottom-right':(21, 7)}
{'top-left':(24, 2), 'bottom-right':(24, 7)}
{'top-left':(28, 2), 'bottom-right':(28, 7)}
{'top-left':(32, 2), 'bottom-right':(32, 7)}
{'top-left':(37, 2), 'bottom-right':(37, 7)}
{'top-left':(41, 2), 'bottom-right':(41, 7)}.
