------------------------------

             Summary: Improve Scalar Function section in Table API documentation
                 Key: FLINK-4597
                 URL: https://issues.apache.org/jira/browse/FLINK-4597
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: Jark Wu
            Assignee: Jark Wu
            Priority: Minor


The function signature in Scalar Function section is a little confusing. Because it's hard
to distinguish keyword and parameters. Such as : {{EXTRACT(TIMEINTERVALUNIT FROM TEMPORAL)}},
user may not know TEMPORAL is a parameter after first glance. I propose to use {{<>}}
around parameters, i.e. {{EXTRACT(<TIMEINTERVALUNIT> FROM <TEMPORAL>)}}
