Could you analyze the table shown in the image and inform me about all the merged cell regions? Use the JSON {'top-left':(x, y), 'bottom-right':(z, w)} to represent each merged area, with (x, y) as the (first row, first column) and (z, w) as the (last row, last column). Note that the x, y, z, w all start from 1.

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