Different merged cells often exist in a table and they can be represented by the JSON {'top-left':(X1, Y1), 'bottom-right':(X2, Y2)}. In this JSON item, '(X1, Y1)' and '(X2, Y2)' 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 areas 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)}.
