Unfortunately I’m not aware of a way to easily configure this through the website at this time. More configurable options in the results table would definitely be a nice enhancement though.
However, if you already developing your own Plone Add-On to extend Senaite or at least can navigate the core code, then it is quite doable on the backend side.
The code for that results table viewlet (in the Senaite 2.x version) lives in senaite.core in bika/lims/browser/analyses/view.py. You can edit which fields you would like to see in self.columns such as is done here.
However, if you are looking for a custom field like the “Reference Value” you mention, then you might need to also adapt the analysis Content Type. This is an example of adding a Inconclusive Boolean field and a AnalysisDateTime String field.
