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':(m, n)}, where '(x, y)' represents the top-left and '(m, n)' 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, 5), 'bottom-right':(1, 6)}
{'top-left':(1, 7), 'bottom-right':(1, 8)}
{'top-left':(1, 9), 'bottom-right':(2, 9)}
{'top-left':(1, 10), 'bottom-right':(2, 10)}
{'top-left':(4, 2), 'bottom-right':(4, 10)}
{'top-left':(9, 2), 'bottom-right':(9, 10)}
{'top-left':(23, 2), 'bottom-right':(23, 10)}
{'top-left':(26, 2), 'bottom-right':(26, 10)}
{'top-left':(29, 2), 'bottom-right':(29, 10)}
{'top-left':(33, 2), 'bottom-right':(33, 10)}
{'top-left':(41, 2), 'bottom-right':(41, 10)}
{'top-left':(44, 2), 'bottom-right':(44, 10)}.
