### How should we improve?
May be we should implement this field as it's a critical field for data
Contributor guide
Research direction
Start by tracing the Lance CreateTable endpoint shown in the issue and follow how its response assembles the location, version, and properties fields. Determine the source of the table version and verify that a successful create response returns the correct non-null version instead of null.
