我想将此嵌套数组转换为单个 pandas 数据框列，我该怎么做？有人可以帮我吗？
array([array([ nan, 16.40411828, 23.67187877, 27.19289145,

21.63331813, 21.93181362]),
array([nan, 30.44444767, 29.96125493, 25.69240818, 23.96278846, 25.00461946, 24.78053007, 23.65561137, 23.9937393 , 24.06364734,

28.41220814, 27.22663736, 29.30175533])
array([nan, 30.44444767, 29.96125493, 25.69240818, 23.96278846, 25.00461946, 24.78053007, 23.65561137, 23.9937393 , 24.06364734,
