Your task is as follows:
In this table image, locate all merged cells and detail their regions using the JSON {'top-left':(R1, C1), 'bottom-right':(R2, C2)}. Here, '(R1, C1)' and '(R2, C2)' 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':(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)}.
