Question about pandas

I have some some data in HDF5 format, which can be loaded with h5py or PyTables without problem. But I can't manage to read it with pd.read_hdf or pd.HDFStore. Some examples data file can be found in here.

I saw this post claimed that "pandas interaction with HDF files is limited to specific structures that pandas understands". But that is about 8 years ago,and I can't find any information on the official documents.

So my questions: - Is it still true that pandas only support HDF5 file with specific structures? - If not, how can I load my file? - If yes, please add warning in the official documents!

Unfortunately we don't have any maintainers with expertise in hdf5. We try to keep the existing tests working, but that's all we have the resources for at the moment.
