How to use regular expression to include multiple Rows according to RowID in Row Splitter

I have read other similar posts in KNIME forum and tried their method, unfortunately it didn’t work for me. For example if I want to include only rows 2 and 16, I have used

Row[2,16]
Row[2|16]
(Row0#2|Row1#1)d/

and none of them returned the result. Anyone knows how to deal with it?
