Why doesn't it work when I use it, it does not interpolate, but just copies a new column, and the missing values are not filled.

In addition, it would be great if more interpolation methods (such as polynomial interpolation, spline interpolation, etc.) can be implemented.

@wwh The new column appears to be a copy and the interpolated data is in the original column.
