Your task is as follows:
In this table image, locate all merged cells and detail their regions using the JSON {'top-left':(x, y), 'bottom-right':(m, n)}. Here, '(x, y)' and '(m, n)' denote the coordinates (row_id, column_id) of the top-left and bottom-right cells of the merged regions, respectively. Keep in mind that row and column IDs 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)}.
