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':(x, y), 'bottom-right':(z, w)},  where (x, y) and (z, w) 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':(3, 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':(3, 2), 'bottom-right':(3, 7)}.
