If you want help in the future I suggest you remain a little more patient. It's the weekend. People don't hang around waiting for you to post a question. We answer questions if and when we have time and we know the answer.
The general answer is yes, of course, it can be done. But we can't give you a specifice answer since you question is so general.
For example, take a look at my code in this posting:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=639189
I made the following changes:
//          addColumn( new TableColumn() );
          TableColumn column = new TableColumn();
          column.setHeaderValue(" ");
          addColumn( column );And then I overrode the following method of the table:
public void columnMarginChanged(ChangeEvent e)
     super.columnMarginChanged(e);
     TableColumn resizingColumn = getTableHeader().getResizingColumn();
     if (resizingColumn != null)
          Dimension d = getPreferredSize();
          d.width = resizingColumn.getWidth();
          setPreferredScrollableViewportSize(d);
}and finally
scrollPane.setRowHeaderView( lineTable );
scrollPane.setCorner(JScrollPane.UPPER_LEFT_CORNER, lineTable.getTableHeader()); // newOf course we have no idea what component you are using for your row header so we can't give a detailed solution, but I suspect you would need to do something like the following:
a) add a mouseListener to your component
b) calculate the change in size of the component using the mouse location changes
c) set the preferred size of your component
d) notify the scroll pane of the change in size. I would look at the setPreferredScrollableViewportSize method of JTable to see what it does.
