Replace column name with the new col object.

The behavior of copy for Column objects is: - copy=True: new class instance with a copy of data and deep copy of meta - copy=False: new class instance with same data and a key-only copy of meta

For mixin columns: - copy=True: new class instance with copy of data and deep copy of meta - copy=False: original instance (no copy at all)

Parameters¶

namestr

Name of column to replace

col~astropy.table.Column or ~numpy.ndarray or sequence

New column object to replace the existing column.

>>> float_a = t['a'].astype(float)
>>> t.replace_column('a', float_a)
