Research direction
Add unit tests for the prependColumn and appendColumn methods in the TestPage class (com.facebook.presto.common.TestPage). Use the existing testing patterns in the file as reference. Run tests via Maven or Gradle to ensure they pass. The issue only requires tests for these two methods; no other changes needed.
