Examine the table in this image and extract any merged cell regions. Please format the merged cell regions as JSON {'top-left':(x, y), 'bottom-right':(m, n)}, with (x, y) indicating the (row_id, column_id) of the top-left cell and (m, n) the bottom-right cell in the merged regions. Remember that the x, y, m, n all start from 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(2, 2), 'bottom-right':(2, 6)}
{'top-left':(4, 2), 'bottom-right':(4, 6)}
{'top-left':(12, 2), 'bottom-right':(12, 6)}
{'top-left':(17, 2), 'bottom-right':(17, 6)}
{'top-left':(25, 2), 'bottom-right':(25, 6)}
{'top-left':(28, 2), 'bottom-right':(28, 6)}
{'top-left':(31, 2), 'bottom-right':(31, 6)}.
