CellEditor på individuelle tabel-celler

Du laver din egen klasse som extender JTable, her overrider du getCellEditor() returnerer det du nu ønsker - har lavet et eksempel så simpelt som jeg kunne.

Det er i den sidste kolonne det sker.



import javax.swing.DefaultCellEditor;
import javax.swing.JComboBox;
import javax.swing.JTable;
import javax.swing.table.TableCellEditor;


public class Different_TableCell_Editor extends javax.swing.JFrame {
   
    public Different_TableCell_Editor() {
        initComponents();
    }
   
    private void initComponents() {
        scroll = new javax.swing.JScrollPane();
        spec_table = new Special_Table_Editor();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        spec_table.setModel(new javax.swing.table.DefaultTableModel(
            new Object [][] {
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null},
                {null, null, null, null}
            },
            new String [] {
                "Title 1", "Title 2", "Title 3", "Title 4"
            }
        ));
        scroll.setViewportView(spec_table);

        getContentPane().add(scroll, java.awt.BorderLayout.CENTER);

        pack();
    }

    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new Different_TableCell_Editor().setVisible(true);
            }
        });
    }

    private javax.swing.JScrollPane scroll;
    private Special_Table_Editor spec_table; 
}






class Special_Table_Editor extends JTable{
   
    public Special_Table_Editor() {
        super();
    }
   
    public TableCellEditor getCellEditor(int row, int column){
        if(row == 0 && column == 3)
            return new DefaultCellEditor(new JComboBox(ar_1));
        if(row == 1 && column == 3)
            return new DefaultCellEditor(new JComboBox(ar_2));
        if(row == 2 && column == 3)
            return new DefaultCellEditor(new JComboBox(ar_3));
        if(row == 3 && column == 3)
            return new DefaultCellEditor(new JComboBox(ar_4));
       
        return super.getCellEditor(row, column);
    }
   
    private String[] ar_1 = new String[]{"Abe", "Hund", "Kat"};
    private String[] ar_2 = new String[]{"Sten", "Grus", "Sand"};
    private String[] ar_3 = new String[]{"Øl", "Vand", "Vin"};
    private String[] ar_4 = new String[]{"10", "100", "1000"};
}
