JTable Cell Focus Listener

[Manfizy]

I need to focus JTable cell such that when enter key is pressed it should focus to the next cell of the same row. If it is the last cell it has to go to the next row.

Your opinions are highly appreciated

So far i have added a keyListener to my table and used the keyPressed method to handle the key events. The funny thing is, when i press enter key i get an error

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Column index out of range

BUT when i use the tab key even when am capturing events for the enter key it works alright:confused:
I just dont know why am getting an error
below is my code

public void keyTyped(KeyEvent e) {}
public void keyReleased(KeyEvent e) {}
public void keyPressed(KeyEvent e) {
        int cols = 2;
        int rows = Xenon.getRowCount();
        int key = e.getKeyCode();
            if (key == KeyEvent.VK_ENTER) {
                int r =Xenon.getSelectedRow();
                int c =Xenon.getSelectedColumn();
              if(c < cols) {
                  setSelectedCol(c + 1);
                   return;
              }
                if(c == cols) {
                  if(r<rows) {
                        setSelectedRow(r + 1);
                        setSelectedCol(0);
                      Xenon.scrollRectToVisible(Xenon.getCellRect(r + 1, 0, true));
                }else {
                setSelectedRow(rows);
              setSelectedCol(cols);
            }
        }
      }
    }
   public void setSelectedCol(int col) {
     if(col == -1)
        return;
            else {
        Xenon.setColumnSelectionInterval(col, col);
       }
      }
 public void setSelectedRow(int row) {
   if(row == -1)
      return;
     else {
   Xenon.setRowSelectionInterval(row, row);
      }
    }

Your ideas are highly appreciated
