Replacing Text in Table headers


I’m trying to trim the name of the column of a table with elasticsearch 5.x as a datasource.
The table gets the name from the json document and does the grouping by the fields in it.
The issue is that using the default loghstash ES template the field we can group on is like this:
What I’d like to do is to remove the .keyword so we only have the name of the field.
Is it possible?
