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':(R1, C1), 'bottom-right':(R2, C2)}, with '(R1, C1)' and '(R2, C2)' 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 region is: {'top-left':(1, 1), 'bottom-right':(1, 2)}.
