The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(2, 2)}
{'top-left':(1, 3), 'bottom-right':(1, 5)}
{'top-left':(3, 2), 'bottom-right':(3, 5)}
{'top-left':(4, 2), 'bottom-right':(4, 5)}
{'top-left':(7, 2), 'bottom-right':(7, 5)}
{'top-left':(10, 2), 'bottom-right':(10, 5)}
