From the provided table image, locate any cells that are merged and list their regions as {'top-left':(X, Y), 'bottom-right':(Z, W)}, with (X, Y) indicating the (row_id, column_id) of top-left cell and (Z, W) 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':(1, 3), 'bottom-right':(1, 4)}.
