Java JTable - Make only one column editable

Question

I was wondering how to make one column of a JTable editable, the other columns have to be non editable.

I have overwritten isCellEditable() but this changes every ce

Answer 1

Reading the remark of Kleopatra (his 2nd time he suggested to have a look at javax.swing.JXTable, and now I Am sorry I didn't have a look the first time :) ) I suggest you follow the link

I searched for an asnwer, and I combined several answers to my own solution: (however, not safe for all solutions, but understandable and quick impelmented, although I recommende to look at the link above)

You can keep it more flexible to set which column is editable or not later on, I used this for exmaple:

    columnsEditable=new ArrayList();
    table=new JTable(new DefaultTableModel(){

            @Override
            public boolean isCellEditable(int row, int col) {
                if(columnsEditable.isEmpty()){
                    return false;
                }
                if(columnsEditable.contains(new Integer(col))){
                    return true;
                }
                return false;
          }
    });

And I used this function to set editable or not:

public void setColumnEditable(int columnIndex,boolean editable){
    if(editable){
        if(!columnsEditable.contains(new Integer(columnIndex))){
            columnsEditable.add(new Integer(columnIndex));
        }
    }else{
        if(columnsEditable.contains(new Integer(columnIndex))){
            columnsEditable.remove(new Integer(columnIndex));
        }
    }
}

Note: of course you have to define columnsEditable and JTable table global in this class:

private JTable table;
private ArrayList columnsEditable;

Note 2: by default all columns are not editable, but that is my desired behaviour. If you whish otherwhise, either add all columns to columnsEditable or change the behaviour completely (make ArrayList columnsNonEditable in stead). In regard to Kleopatra's remark: its better not to use this last suggestion (but it depends on the used tablemodel and what you do in the rest of your program).
