Provide me with the row number and column number for the table shown in this image. Return the result as JSON in the format {"row_number": "m", "column_number": "n"}, e.g., {"row_number": "12", "column_number": "7"}.

There are 8 rows and 10 columns in the table. So, the final answer is {"row_number": "8", "column_number": "10"}.
