PyTables (neither 1.x or 2.x series) doesn't implement support for arrays of compounds, sorry about that. It does support, however, compounds of compounds (nested tables in PyTables jargon) and compounds of arrays, so instead of declaring a column as an array of compounds, you may want to declare it as a compound of arrays.
