[GitHub] [spark] viirya commented on pull request #32354: [SPARK-35232][SQL] Nested column pruning should retain column metadata

   To test the above change, this also added the logic of column projection in InMemoryTable. Without the fix DSV2CharVarcharDDLTestSuite will fail.
   
   Does it mean if only applying `SchemaPruning` change without `InMemoryTable`, `DSV2CharVarcharDDLTestSuite` will fail?
