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':(z, w)}, with '(x, y)' and '(z, w)' 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 areas are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(1, 2), 'bottom-right':(2, 2)}
{'top-left':(1, 3), 'bottom-right':(2, 3)}
{'top-left':(1, 4), 'bottom-right':(1, 6)}
{'top-left':(1, 7), 'bottom-right':(1, 9)}
{'top-left':(6, 1), 'bottom-right':(6, 3)}
{'top-left':(7, 1), 'bottom-right':(7, 9)}.
