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':(A, B), 'bottom-right':(C, D)},  where (A, B) and (C, D) 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':(2, 2), 'bottom-right':(2, 3)}
{'top-left':(2, 4), 'bottom-right':(2, 8)}.
