    Description

      When we run the TableAPI as follows:

      val windowedTable = table
      .window(Over partitionBy 'c orderBy 'proctime preceding UNBOUNDED_ROW as 'w)
      .select('c, "countFun(b)" over 'w as 'mycount, weightAvgFun('a, 'b) over 'w as 'wAvg)

      We get the error:

      org.apache.flink.table.api.TableException: The over method can only using with aggregation expression.

	at org.apache.flink.table.api.scala.ImplicitExpressionOperations$class.over(expressionDsl.scala:469)
	at org.apache.flink.table.api.scala.ImplicitExpressionConversions$LiteralStringExpression.over(expressionDsl.scala:756)

      The reason is, the `over` method of `expressionDsl` not parse the String case.
      I think we should fix this before 1.3 release.
