Here's what I need you to do:
In the image of this table, identify all the merged cells. Provide the coordinates of these merged regions in the JSON {'top-left':(x, y), 'bottom-right':(m, n)}, with '(x, y)' and '(m, n)' indicating the (row_id, column_id) of the top-left and bottom-right cells, respectively. Remember, row and column numbering starts at 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 3)}
{'top-left':(3, 2), 'bottom-right':(3, 3)}
{'top-left':(8, 2), 'bottom-right':(8, 3)}.
