I'd like to know the total number of rows and columns in the provided table. Output the final answer in the JSON format {"row_number": "m", "column_number": "n"}. For instance, if the table has 5 rows and 4 columns, the answer would be {"row_number": "5", "column_number": "4"}

This table has 9 rows and 5 columns. Thus, the final answer is {"row_number": "9", "column_number": "5"}.
