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 area is: {'top-left':(1, 1), 'bottom-right':(1, 4)}.
