In tables, merged cells are often found and we can denote them as JSON {'top-left':(x, y), 'bottom-right':(z, w)}, with '(x, y)' and '(z, w)' indicating the (row_id, column_id) of the top-left and bottom-right cells of the merged region. Please scan the table image provided, find all occurrences of merged cells, and return their coordinates in the stated format. It's important to remember that row and column IDs begin from 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(3, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 3)}
{'top-left':(1, 4), 'bottom-right':(1, 5)}.
