I'd like to know the total number of rows and columns in the provided table. The JSON format {"row_number": "m", "column_number": "n"} should be utilized to display the ultimate result.

There are 8 rows and 12 columns in the table. So, the final answer is {"row_number": "8", "column_number": "12"}.
