A table may have multiple merged cells and we can represent a merged cell region by a JSON {'top-left':(X1, Y1), 'bottom-right':(X2, Y2)}. Here, '(X1, Y1)' and '(X2, Y2)' denote the coordinates (row_id, column_id) of the top-left and bottom-right cells of the merged regions, respectively. Now, based on the shown table image, please find all merged cells in this table and return their representations in the above format. Keep in mind that row and column IDs start from 1.

The merged cell areas 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':(3, 2), 'bottom-right':(3, 5)}.
