You probably need to use a TableModel (Oracle's tutorial here)

How implements your own TableModel

public class FootballClubTableModel extends AbstractTableModel {
  private List clubs ;
  private String[] columns ; 

  public FootBallClubTableModel(List aClubList){
    super();
    clubs = aClubList ;
    columns = new String[]{"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};
  }

  // Number of column of your table
  public int getColumnCount() {
    return columns.length ;
  }

  // Number of row of your table
  public int getRowsCount() {
    return clubs.size();
  }

  // The object to render in a cell
  public Object getValueAt(int row, int col) {
    FootballClub club = clubs.get(row);
    switch(col) {
      case 0: return club.getPosition();
      // to complete here...
      default: return null;
    }
  }

  // Optional, the name of your column
  public String getColumnName(int col) {
    return columns[col] ;
  }

}

You maybe need to override anothers methods of TableModel, depends on what you want to do, but here is the essential methods to understand and implements :)
Use it like this

List clubs = getFootballClub();
TableModel model = new FootballClubTableModel(clubs);
JTable table = new JTable(model);

Hope it help !
