Your task is as follows:
In this table image, locate all merged cells and detail their regions using the JSON {'top-left':(X, Y), 'bottom-right':(Z, W)}. Here, '(X, Y)' and '(Z, W)' denote the coordinates (row_id, column_id) of the top-left and bottom-right cells of the merged regions, respectively. Keep in mind that row and column IDs start from 1.

This table does not contain any merged cells.
