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"
 }
