Columns don't update in JTable

I'm using a JTable with AbstractTableModel:

_model = new AbstractTableModel() {

            @Override
            public int getColumnCount() {
                return _columns.size();
            }
            @Override
            public int getRowCount() {
                return _data.size();
            }
            @Override
            public Object getValueAt(int row, int col) {
                return _data.get(row)[col];
            }

            @Override
            public String getColumnName(int i) {
                return _columns.get(i);
            }
        };

When rows and columns change, calling table.revalidate() only shows changes to rows. Columns are exactly the same as before. Is there a way to force update for the whole table?

If you change columns you should call fireTableStructureChanged on the model.

shouldn't it be 

   @Override
                public Object getValueAt(int row, int col) {
                    return _data.get[row][col];
                }
