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);
I used this and it worked : it is very simple and works fine.
JTable myTable = new JTable();
myTable.setEnabled(false);
just add
table.setEnabled(false);
it works fine for me.
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()));
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.
table.setDefaultEditor(Object.class, null);
