如何使 JTable 不可编辑

You can use a TableModel.

Define a class like this:

public class MyModel extends AbstractTableModel{
//not necessary
}

actually isCellEditable() is false by default so you may omit it. (see: http://docs.oracle.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html)

Then use the setModel() method of your JTable.

JTable myTable = new JTable();
myTable.setModel(new MyModel());

You can override the method isCellEditable and implement as you want for example:

//instance table model
DefaultTableModel tableModel = new DefaultTableModel() {


@Override
public boolean isCellEditable(int row, int column) {
//all cells false
return false;
}
};


table.setModel(tableModel);

or

//instance table model
DefaultTableModel tableModel = new DefaultTableModel() {


@Override
public boolean isCellEditable(int row, int column) {
//Only the third column
return column == 3;
}
};


table.setModel(tableModel);

Note for if your JTable disappears

If your JTable is disappearing when you use this it is most likely because you need to use the DefaultTableModel(Object[][] data, Object[] columnNames) constructor instead.

//instance table model
DefaultTableModel tableModel = new DefaultTableModel(data, columnNames) {


@Override
public boolean isCellEditable(int row, int column) {
//all cells false
return false;
}
};


table.setModel(tableModel);

just add

table.setEnabled(false);

it works fine for me.

If you are creating the TableModel automatically from a set of values (with "new JTable(Vector, Vector)"), perhaps it is easier to remove editors from columns:

JTable table = new JTable(my_rows, my_header);


for (int c = 0; c < table.getColumnCount(); c++)
{
Class<?> col_class = table.getColumnClass(c);
table.setDefaultEditor(col_class, null);        // remove editor
}

Without editors, data will be not editable.

create new DefaultCellEditor class :

public static class Editor_name extends DefaultCellEditor {
public Editor_name(JCheckBox checkBox) {
super(checkBox);
}
@Override
public boolean isCellEditable(EventObject anEvent) {
return false;
}
}

and use setCellEditor :

JTable table = new JTable();
table.getColumn("columnName").setCellEditor(new Editor_name(new JCheckBox()));

table.setDefaultEditor(Object.class, null);

I used this and it worked : it is very simple and works fine.

JTable myTable = new JTable();
myTable.setEnabled(false);
