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':(2, 5)}
{'top-left':(1, 6), 'bottom-right':(2, 6)}
{'top-left':(1, 7), 'bottom-right':(2, 7)}
{'top-left':(3, 2), 'bottom-right':(3, 7)}
{'top-left':(4, 2), 'bottom-right':(4, 7)}
{'top-left':(7, 2), 'bottom-right':(7, 7)}
