   ```rs
   let df = df.select(vec![
           col("?table?.key").alias("key"),
           col("?table?.size").alias("size"),
           col("?table?.last_modified").alias("last_modified"),
       ])?;
   ```
   
   ```
   Error: Schema error: No field named '?table?.key'. Valid fields are '?table?'.'key', '?table?'.'size',
   ..
   ```
   
   Also tried `col("'?table?'.'key'").alias("key"),`
