Return the cells' value in the subsequent table rows or columns:
the 3rd column,
the 7th row,
the 8th row,
the 4th row,
the 1st column,

The cells of every row or column should be presented in the JSON format of {"row_id/column_id":"<row or column index>", "cell_list":"<a list of cells in this row/column>"}, e.g., {"row_id":"3", "cell_list": ["xxx", "yyy", "zzz"]}.

The cell values of target rows or columns are as follows:
For the 3rd column: {"column_id": "3", "cell_list": ['decimal128', '1', '5', '12', '110', '128', '34', '12288', '6144', '−6143', '−6176']}
For the 7th row: {"row_id": "7", "cell_list": ['7', '16', '34', 'p = 3×t/10+1 = 9×k−2', 'Coefficient size (decimal digits)']}
For the 8th row: {"row_id": "8", "cell_list": ['192', '768', '12288', '3×2w = 48×4k', 'Exponent range']}
For the 4th row: {"row_id": "4", "cell_list": ['6', '8', '12', 'w = 2×k + 4', 'Exponent continuation field (bits)']}
For the 1st column: {"column_id": "1", "cell_list": ['decimal32', '1', '5', '6', '20', '32', '7', '192', '96', '−95', '−101']}
