如何在 pandas 中给定行索引和列名称的特定单元格上色？

columns_to_color = {  0: ['col1', 'col2', 'col9'],  # Columns 1, 2 and 9 should be colored for row 0  1: ['col1', 'col5', 'col8'],  # Columns 1, 5 and 8 should be colored for row 1  2: ['col3', 'col4', 'col7'],  # Columns 3, 4 and 7 should be colored for row 2  .......

df.style.apply(    lambda row: [        'font-weight: bold' if col in columns_to_color[row.name] else ''        for col in row.index],    axis=1)

df = pd.DataFrame({f'col{n}': range(10*n, 10*n + 3) for n in range(10)})
