Apply Filter on Data source Drag drop repeating section.

Just click on the repeating table on little upper left square will select all table and go to rules and add formatting rule that..

If field(Form filed) is not equal to field(Data source field) then hide this control..

field(Form filed)  & (Data source field) having same data.

Will filter your data and you will see only the data based on your filtered formatting condition..

I have been looking for a while and finally I have got this solution..

Happy Sharepointing...Have a nyc day..:p
