    Description

      e.g.

      "columnExprMap:":{  
                "_col0":"0:Column[_col0]",
                "_col1":"0:Column[_col1]",
                "_col2":"1:Column[_col0]",
                "_col3":"1:Column[_col1]"
        }
      

      It is better formatted as:

      "columnExprMap:":{  
                   "_col0":"0:_col0",
                   "_col1":"0:_col1",
                   "_col2":"1:_col0",
                   "_col3":"1:_col1"
       }
