From the provided table image, locate any cells that are merged and list their regions as {'top-left':(R1, C1), 'bottom-right':(R2, C2)}, with (R1, C1) indicating the (row_id, column_id) of top-left cell and (R2, C2) the bottom-right cell. Both the row_id and column_id start from 1.

The merged cell regions 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, 3)}
{'top-left':(8, 2), 'bottom-right':(8, 3)}
{'top-left':(11, 2), 'bottom-right':(11, 3)}
