Tell me how many rows and columns exist in the given 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"}

There are 20 rows and 5 columns in the table. So, the final answer is {"row_number": "20", "column_number": "5"}.
