in example, returns columns header contains "id". thinking it's nr==fnr part causing problem. couldn't understand means 

 cols=cols (cols?"|":"")$1  next

could me understand code? if possible, fix code too?

the problem match method takes regex second argument.

change if normal comparison (==) should help.
