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':(3, 2), 'bottom-right':(3, 4)}
{'top-left':(4, 2), 'bottom-right':(4, 4)}
{'top-left':(7, 2), 'bottom-right':(7, 4)}
{'top-left':(11, 2), 'bottom-right':(11, 4)}
{'top-left':(22, 2), 'bottom-right':(22, 4)}
{'top-left':(25, 2), 'bottom-right':(25, 4)}
{'top-left':(31, 2), 'bottom-right':(31, 4)}
{'top-left':(37, 2), 'bottom-right':(37, 4)}.
