Examine the table in this image and extract any merged cell regions. Please format the merged cell regions as JSON {'top-left':(R1, C1), 'bottom-right':(R2, C2)}, with (R1, C1) indicating the (row_id, column_id) of the top-left cell and (R2, C2) the bottom-right cell in the merged regions. Remember that the R1, C1, R2, C2 all start from 1.

The merged cell regions are as follows:
{'top-left':(2, 1), 'bottom-right':(2, 9)}
{'top-left':(19, 1), 'bottom-right':(19, 9)}
{'top-left':(36, 1), 'bottom-right':(36, 9)}.
