JTable中的JCheckBox只显示True / False值

Question

我创建了一个JTable并覆盖了返回类型以在第一个Cell中显示JCheckBox，但我显示了true / false值。我怎么能看到Box而不是价值呢？

public JTable table = new JTable(new DefaultTableModel(new Object[]{"", "ID", "Cod. Proveedor", "Empresa", "Nombre", "Responsable", "F. Entrada", "H. Entrada", "F. Salida", "H. Salida", "Nº Tarjeta", "Tipo"}, 0))
{
    private static final long serialVersionUID = 1L;
    @Override
    public Class getColumnClass(int column) {
        switch (column) {
            case 0:
                return Boolean.class;   
            case 1:
                return String.class;
            case 2:
                return String.class;
            case 3:
                return String.class;
            case 4:
                return String.class;
            case 5:
                return String.class;
            case 6:
                return String.class;
            case 7:
                return String.class;
            case 8:
                return String.class;
            case 9:
                return String.class;
            case 10:
                return String.class;
            case 11:
                return String.class;
            default:
                return String.class;
        }
    }
};
public JScrollPane sP = new JScrollPane(table);
DefaultTableModel model = (DefaultTableModel) table.getModel();
model.addRow(new Object[]{false, result.getString("ID").trim(), result.getString("CODPROV").trim(), result.getString("EMPRESA").trim(), result.getString("NOMBRE").trim(), result.getString("RESPONS").trim(), fEntrada, hEntrada, fSalida, hSalida, result.getString("NTARJETA").trim(), result.getString("TIPO").trim(), false });

Answer 1

在JTable中，如果要在每行的特定列中添加JCheckBox，则只需将该列的columntype添加为boolean，并且每当向表中添加任何行时，只需在其中添加true或false（布尔值）即可单元格。

请参考下面的代码片段，以将列数据类型设置为boolean add复选框。

Class[] columnTypes = new Class[] { Boolean.class, Object.class, Object.class, String.class, Object.class };

        public Class getColumnClass(int columnIndex) {
            return columnTypes[columnIndex];
        }

Answer 2

 JCheckBox check=new JCheckBox();

    jTable1.getColumnModel().getColumn(0).setCellEditor(new DefaultCellEditor(check)); 

尝试使用此代码作为复选框

 String aa[]={"yellow","15","50"};
    JComboBox j2=new JComboBox(aa);

    j2.setEditable(true);
    jTable1.getColumnModel().getColumn(1).setCellEditor(new DefaultCellEditor(j2)); 

如果您不使用comboBox ：）
