-----------------------------------
Summary: [Python] Add pyarrow.Table method that replaces a column
with a new supplied column
Key: ARROW-2699
URL: https://issues.apache.org/jira/browse/ARROW-2699
Project: Apache Arrow
Issue Type: New Feature
Components: Python
Reporter: Wes McKinney
Fix For: 0.10.0
This method would produce a new table since table objects are immutable.
Example:
{code}
new_column = table.column(name).cast(pa.timestamp('ms'))
new_table = table.set_column(name, new_column)
{code}
