----------------------------------
Summary: [C++] Adding a column to an empty Table fails
Key: ARROW-1865
URL: https://issues.apache.org/jira/browse/ARROW-1865
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Uwe L. Korn
If we remove a column from a table and add new column (probably a casted
version of it), it is rejected as the Table {{num_rows}} was reset to 0:
{code}
Invalid: Added column's length must match table's length. Expected length 0 but
got length 1
{code}
