If the label is valid and if the size of data is the same as existing columns, then replaces the specified column with a copy of data in data and sets its shape. If the label is not valid or the sizes differ, then throws a DataSourceException.

Replaces the data in column index.
If index is in a valid range and if the size of data is the same as existing columns, then replaces the specified column with a copy of data in data and sets its shape. If index is not a valid range or the sizes differ, then throws a DataSourceException. In neither case is the FITS file modified.

Replaces the data in column index.
If index is in a valid range and if the size of data is the same as existing columns, then replaces the specified column with a copy of data in data and sets it shape to rank 1 array. If index is not a valid range or the sizes differ, then throws a DataSourceException. In neither case is the FITS file modified.
