The H5_BROWSER is actually quite decent for reading
HDF5 data files. MUCH better than the HDF_BROWSER.

No, my experience with HDF5 is extremely limited. I do notice
that in a tutorial for creating tables:
http://hdf.ncsa.uiuc.edu/HDF5/Tutor/h5table.html#01
that a function H5TBread_table is called. Nothing like that
seems to be available in IDL, so perhaps tables are not
supported. A quick look at the IDL documentation doesn't
shed any light.
Cheers,
David
