This image presents a table, and I'd like to know its row and column numbers. 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 19 rows and 13 columns. Thus, the final answer is {"row_number": "19", "column_number": "13"}.
