Hi Everyone,
I create an expandable earray of Nx4 columns. Some columns require float64 datatypes, the others can be managed with int32. Is it possible to vary the data types among the columns? Right now I just use one (float64, below) for all, but it takes huge disk space for (>10 GB) files.
Foe example, how can I mention column 1-2 elements are int32 and 3-4 elements are float64?

a = f1.create_earray(f1.root, "dataset_1", atom=tables.Float32Atom(), shape=(0, 4))
