To do this interactively, go to the area at the top of the Row State column(the column that has the row numbers). Right click and select
Row Selection+>Select Where

Then in the dialog that is opened, specify to find rows where Label Contains "Rpp"

It will then select the rows you want

Now go to
Tables=>Subset
The Subset dialog window will open. Specify to only subset Selected Rows, and all columns

It will then create the new table you want

Repeat the same process for your Wig_350 subset you want.
If you want to do this using JSL, the below will do the same
Names Default To Here( 1 );
dt = Current Data Table();
dt << select where( Contains( :label, "Rpp" ) == 1 );
dt << subset( selected rows( 1 ), selected columns( 0 ) );
dt << select where( Contains( :label, "Wig_350" ) == 1 );
