This question does not have much context so i'm not sure if my reply will assist here or not but I would use
If first()=0 then 'show' else 'hide' end
and put this calculated field on the filters tab. Select to show only "show".
This assumes that the second row of data does need to be 'in the view' so to speak in order to have the calculation appear and work.
let us know if this works or you need more assistance.
