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':(X1, Y1), 'bottom-right':(X2, Y2)}, with '(X1, Y1)' and '(X2, Y2)' 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':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 5)}
{'top-left':(1, 6), 'bottom-right':(1, 9)}
{'top-left':(3, 2), 'bottom-right':(3, 5)}
{'top-left':(3, 6), 'bottom-right':(3, 9)}
{'top-left':(5, 2), 'bottom-right':(5, 9)}
{'top-left':(8, 2), 'bottom-right':(8, 9)}
{'top-left':(17, 2), 'bottom-right':(17, 9)}
{'top-left':(22, 2), 'bottom-right':(22, 9)}
{'top-left':(27, 2), 'bottom-right':(27, 9)}
{'top-left':(31, 2), 'bottom-right':(31, 9)}
{'top-left':(36, 2), 'bottom-right':(36, 9)}
{'top-left':(39, 2), 'bottom-right':(39, 9)}.
