Look at the table in the image and show any merged cells, specifying their locations with the JSON format of {'top-left':(X1, Y1), 'bottom-right':(X2, Y2)}, where X1, Y1, X2 and Y2 are indices (starting from 1) of the first row, the first column, the last row and the last column, respectively.

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