Please perform the following task:
Examine the provided table image to identify all cells that are merged. Report back the merged cell areas using the JSON {'top-left':(x, y), 'bottom-right':(z, w)}, where '(x, y)' represents the top-left and '(z, w)' the bottom-right cell's (row_id, column_id) in each merged region. Note that both row and column IDs begin at 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(1, 2), 'bottom-right':(1, 3)}
{'top-left':(1, 4), 'bottom-right':(1, 5)}
{'top-left':(1, 6), 'bottom-right':(1, 7)}.
