   Hmm, is `TableFunction` an expression 🤔? 
   refer to https://docs.snowflake.com/en/sql-reference/functions-table.html
   The sql looks usually like 
   ```
   select doi.date as "Date", record_temperatures.city, record_temperatures.temperature
       from dates_of_interest as doi,
            table(record_high_temperatures_for_date(doi.date)) as record_temperatures;
   ```
