I am generating a parser using below command

I am unable to get the parent token for the current token using ParserRuleContext, I can't see getParent() function as mentioned in documentations
(https://github.com/antlr/antlr4/blob/dev/runtime/JavaScript/src/antlr4/context/ParserRuleContext.d.ts)

Sorry I misread your question.
Not sure what you mean by parent token. This concept does not exist in ANTLR.

For example, for the below block of code
I need to get 'table' as the parent of 'column' token and 'column' as the parent of 'dataType' token

This is a multi-step navigation in the parse tree. We don't know your grammar, but obviously there would need to be a rule that recognizes the entire input from table to string in the last line. To get 'Dim Legal Entity', you would need to navigate up the parse tree to the node that contains the input, then down the parse tree to the leaf node 'Dim Legal Entity', then get the token for the leaf.
