    Das ist so nicht möglich. Als Workaround könnte ich dir empfehlen dich mit dem RowHeader von JScrollPane auseinanderzusetzen. Für eine Scrollpane lassen sich nämlich Spalten- und Zeilen-Header vergeben. In deinem Fall also setRowHeaderView mit der zweiten TextArea als Parameter ... versuchen kannst du es ja mal ...
