Table:
Day	Number of books

Sunday	91

Monday	94

Tuesday	98

Wednesday	95

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 6 rows and 2 columns. Thus, the final answer is {"row_number": "6", "column_number": "2"}.
