From the provided table image, locate any cells that are merged and list their areas as {'top-left':(x, y), 'bottom-right':(m, n)}, with (x, y) indicating the (row_id, column_id) of top-left cell and (m, n) the bottom-right cell. Both the row_id and column_id start from 1.

The merged cell areas are as follows:
{'top-left':(1, 1), 'bottom-right':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(3, 2)}
{'top-left':(1, 3), 'bottom-right':(1, 5)}
{'top-left':(1, 6), 'bottom-right':(1, 8)}
{'top-left':(1, 9), 'bottom-right':(1, 11)}
{'top-left':(2, 3), 'bottom-right':(3, 3)}
{'top-left':(2, 4), 'bottom-right':(2, 5)}
{'top-left':(2, 6), 'bottom-right':(3, 6)}
{'top-left':(2, 7), 'bottom-right':(2, 8)}
{'top-left':(2, 9), 'bottom-right':(3, 9)}
{'top-left':(2, 10), 'bottom-right':(2, 11)}
{'top-left':(5, 2), 'bottom-right':(5, 11)}
{'top-left':(8, 2), 'bottom-right':(8, 11)}.
