This image shows a table. Determine whether this table contains merged cells and output merged cell regions with the JSON format of {'top-left':(X1, Y1), 'bottom-right':(X2, Y2)}, where X1, Y1, X2 and Y2 represent the indices of the first row, the first column, the last row, and the last column in the merged region. Row and column indices are numberd from 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(2, 2), 'bottom-right':(2, 4)}
{'top-left':(3, 2), 'bottom-right':(3, 4)}
{'top-left':(14, 2), 'bottom-right':(14, 4)}
{'top-left':(25, 2), 'bottom-right':(25, 4)}
{'top-left':(36, 2), 'bottom-right':(36, 4)}.
