:func:`pyarrow.concat_tables`:
cast data from one type to another (if `promote=True`). In such cases the
data
will need to be copied and an extra cost will occur.
+Adding a column to an existing Table
+====================================
+
+If you have a table it is possible to extend its columns using
+:meth:`pyarrow.Table.append_column`
+
+Suppose we have a table with oscar nominations for each actress
+
+.. testcode::
+
+ import pyarrow as pa
+
+ oscar_nominations = pa.table([
+ ["Meryl Streep", "Katharine Hepburn"],
+ [21, 12]
+ ], names=["actor", "nominations"])
Review comment:
Right, the only reason I am pointing this out is because of the
inconsistency (the sentence above says "actress" but the table says "actor").
