Kłopot ze stworzeniem modelu.

Zerknijcie na poniższy kod.

1.Czy to jest prawidłowy sposób stworzenia modelu
2.Jezeli tak to nie widzę tabeli.

package program;

import javax.swing.JPanel;
import javax.swing.GroupLayout;
import javax.swing.GroupLayout.Alignment;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.LayoutStyle.ComponentPlacement;
import javax.swing.table.AbstractTableModel;

import java.awt.FlowLayout;
import javax.swing.BoxLayout;

public class PanelStatystyki extends JPanel
{
	private JTable tabeleStatystyki;
	private PanelPrzebieguCwiczen panel;
	
	private GlownaRamka ramka;
	private JScrollPane przewijanieTabeli;
	private String[] nazwaKolumn;
	private Object[][] komorki;
	
	public PanelStatystyki(GlownaRamka main) 
	{
	this.ramka = main;	
		
        nazwaKolumn = new String[] {"data","wiek","waga"};
        komorki = new Object[][] {{"12-03-2014",29,85}, {"01-03-2015",30,80},{"02-06-2016",31,75}};
	    setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5));
	    
	    tabeleStatystyki = new JTable(new TabelaStatystyki(komorki,nazwaKolumn));
	   
		przewijanieTabeli = new JScrollPane(tabeleStatystyki);
		add(przewijanieTabeli);
	}
	
	class TabelaStatystyki extends AbstractTableModel 
	
	{    
		private String[] nazwaKolumn;
	    private Object[][] komorki;
		 
		public TabelaStatystyki(Object[][]komorki,String[]nazwaKolumn)
		{
		this.komorki = komorki;
		this.nazwaKolumn = nazwaKolumn;
		}
		
		@Override
		public int getColumnCount() {
			
			return 0;
		}

		@Override
		public int getRowCount() {
			// TODO Auto-generated method stub
			return 0;
		}

		@Override
		public Object getValueAt(int arg0, int arg1) {
			// TODO Auto-generated method stub
			return null;
		}	
	}	
}

Sposób jest w zasadzie poprawny, ale diabeł tkwi w szczegółach. U Ciebie jest tak:

        @Override
        public int getColumnCount() {
 
            return 0;
        }
 
        @Override
        public int getRowCount() {
            // TODO Auto-generated method stub
            return 0;
        }

Twoja tabela "chwali się", że ma 0 kolumn i o wierszy. Co byś chciał zobaczyć?

        @Override
        public int getColumnCount() {
 
            return nazwaColumn.length;;
        }
 
        @Override
        public int getRowCount() {
            // TODO Auto-generated method stub
            return komorki.length;
        }
        @Override
        public Object getValueAt(int row, int col) {
            // TODO Auto-generated method stub
            return komorki[row][col];
        }
        @Override
        public String getColumnName(int col) 
        {
            return nazwaKolumn[col];
        }

Ok tabela jest ale zawartości nie pokazuje a w konstruktorze umiesciłem

 
nKolumn = new String[] {"data","wiek","waga"};
nKomorki = new Object[][] {{"12-03-2014",29,85}, {"01-03-2015",30,80},{"02-06-2016",31,75}};
	    
tabeleStatystyki = new JTable(new TabelaStatystyki(nKomorki,nKolumn));
	   
przewijanieTabeli = new JScrollPane(tabeleStatystyki);

A po co to umieściłeś? Miałeś tylko zmienić metody getColumnCount, getRowCount, getValueAt i dopisać metodę getColumnName (to co napisałem w poście).
Czy w klasie GlownaRamka masz coś w rodzaju add(new PanelStatystyki(this));?

Wszystko działa, dzieki

Co jest nie tak, że metoda

 
@Override
	        public String getColumnName(int kolumny) 
	        {   
	        	return nazwaKolumn[kolumny];
	              
	            
	        }

zwraca mi

Błąd jest w kodzie, którego nie dałeś.

at program.PanelStatystyki$TabelaStatystyki.getColumnName(PanelStatystyki.java:368)

Plik PanelStatystyki.java jest dużo krótszy.
A za kod

           nKomorki = new Object[][] {
                {null, null, null, null},
                {null, null, null, null},
...

to po śmierci pójdziesz do piekła, a za życia uschnie Ci ręka, żebyś nie mógł tego powtórzyć.

Krótszy poniewaz wyrzuciłem śmieci z GroupLayout. Wrzuce cały w takim razie. A te nulle to zdawałem sobie sprawe że pewnie tak sie nie robi ale uzyłem edytora design do tego. W takim razie jak stworzyc tabele ktora ma 4 kolumny {A,B,C,D} i ok 100 pustych wierszy w ktorych uzytkownik moze sobie wpisac dane ?

1. Przemyśl tę funkcję;

        @Override
        public int getColumnCount() {
 
            return komorki.length;
        }

Podpowiedź, ile jest kolumn w tabeli, 4 czy 100?
2. Jeśli musisz korzystać w modelu z tablicy, to

           nKomorki = new Object[100][]; 
           for(int i=0;i<100;i++)
           {
               nKomorki[i] = new Object[] {null,null,null,null};
           }
