Different merged cells often exist in a table and they can be represented by the JSON {'top-left':(x, y), 'bottom-right':(m, n)}. In this JSON item, '(x, y)' and '(m, n)' are the (row_id, column_id) coordinates for the top-left and bottom-right cells in the merged region, respectively. Please examine the provided table image, identify all merged cells, and return their details using the above-mentioned format. Remember, the numbering for both rows and columns starts at 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)}
{'top-left':(1, 6), 'bottom-right':(1, 7)}.
