Different merged cells often exist in a table and they can be represented by the JSON {'top-left':(A, B), 'bottom-right':(C, D)}. In this JSON item, '(A, B)' and '(C, D)' 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':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 4)}
{'top-left':(1, 5), 'bottom-right':(1, 7)}
{'top-left':(3, 2), 'bottom-right':(3, 7)}
{'top-left':(4, 2), 'bottom-right':(4, 7)}
{'top-left':(10, 2), 'bottom-right':(10, 7)}
{'top-left':(11, 2), 'bottom-right':(11, 7)}.
