How to make JTable cell editable/noneditable dynamically?

Question

Is there any way to make non editable cell dynamically in jtable ? Whenever user gives input like false, i want to make non editable cell...I have seen in DefaultTableModel

Answer 1

I had similar problems to figure out how to enable/disable editing of a cell dynamically (in my case based on occurences in a database.) I did it like this:

jTableAssignments = new javax.swing.JTable() {
public boolean isCellEditable(int rowIndex, int colIndex) {
    return editable;
}};

That of course overrides isCellEditable. The only way I could make that work by the way, was to add the declaration to the instantiation of the tabel itself and not the table model.

Then I declared editable as a private boolean that can be set e.g.:

    private void jTableAssignmentsMouseClicked(java.awt.event.MouseEvent evt) {                                               
    if(jTableAssignments.getSelectedRow() == 3 & jTableAssignments.getSelectedColumn() == 3) {
        editable = true;
    }
    else {
        editable = false;
    } 

}                                              

And it works quite well.
