Based on this table picture, can you identify any merged cells and give their coordinates in the JSON format {'top-left':(R1, C1), 'bottom-right':(R2, C2)}, where (R1, C1) and (R2, C2) correspond to the top-left and bottom-right (row_id, column_id) of the merged area? The row_id and column_id should start from 1 rather than 0.

The merged cell areas are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(2, 2), 'bottom-right':(2, 3)}
{'top-left':(3, 2), 'bottom-right':(3, 4)}.
