"Whatever Happened To Love"

I need you to conduct the following task:
Given this table image, find all merged table cells and return merged regions with the JSON {'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. You should remember that row id and column id 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, 11)}
{'top-left':(1, 12), 'bottom-right':(2, 12)}
{'top-left':(1, 13), 'bottom-right':(2, 13)}
{'top-left':(3, 1), 'bottom-right':(7, 1)}
{'top-left':(3, 13), 'bottom-right':(7, 13)}
{'top-left':(8, 1), 'bottom-right':(9, 1)}
{'top-left':(8, 13), 'bottom-right':(9, 13)}
{'top-left':(10, 1), 'bottom-right':(11, 1)}
{'top-left':(10, 13), 'bottom-right':(11, 13)}.
