A merged cell in a table could be represented by the JSON {'top-left':(R1, C1), 'bottom-right':(R2, C2)}, where '(R1, C1)' and '(R2, C2)' signify the (row_id, column_id) of the top-left and bottom-right cells in the merged area. Using the shown table image, locate all merged cells and provide their coordinates in this format. Bear in mind that row and column IDs begin from 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':(3, 2), 'bottom-right':(3, 5)}
{'top-left':(7, 2), 'bottom-right':(7, 5)}.
