This format allows for specification of key table and column meta-data, in particular the data type and unit. For details see: https://github.com/astropy/astropy-APEs/blob/master/APE6.rst. Examples -------- >>> from astropy.table import Table >>> ecsv_content = '''# %ECSV 0.9 ... # --- ... # datatype: ... # - {name: a, unit: m / s, datatype: int64, format: '%03d'} ... # - {name: b, unit: km, datatype: int64, description: This is column b} ... a b ... 001 2 ... 004 3 ...

This is a hook to allow updating the table columns after name filtering but before setting up to write the data. This is currently only used by ECSV and is otherwise just a pass-through.
