title: Create nested table using presto?
body: <p>If I have a spark schema of this structure,</p>
  <pre><code>root
   |-- id: long (nullable = true)
   |-- firstname: string (nullable = true)
   |-- lastname: string (nullable = true)
   |-- orders: array (nullable = true)
   |    |-- element: struct (containsNull = true)
   |    |    |-- id: long (nullable = true)
   |    |    |-- price: double (nullable = true)
   |    |    |-- userid: long (nullable = true)
  </code></pre>
  <p>How to create a table with this schema,
  I tried with this query,</p>
  <pre><code>CREATE TABLE iceberg.test.order (
  id BIGINT,
  firstName VARCHAR,
  lastName VARCHAR,
  orders ROW(
      id BIGINT,
      price double,
      userid BIGINT
          )
                  )
  WITH (
    format = 'PARQUET'
  )
  </code></pre>
