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':(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. You should remember that row id and column id start from 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 3)}
{'top-left':(1, 4), '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':(1, 11)}
{'top-left':(3, 1), 'bottom-right':(3, 11)}
{'top-left':(12, 1), 'bottom-right':(12, 11)}
{'top-left':(21, 1), 'bottom-right':(21, 11)}.
