TreeTable First column is not editable by ColoredTreeCellRenderer

i have add this code when tree table is created,

public boolean isCellEditable(int row, int column){
    return true;
}

i also add code to make table like tree!

class Renderer extends ColoredTreeCellRenderer {
        @Override
        public void customizeCellRenderer(@NotNull JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) {
            //解决TreeTable key加上>
            CustomNode node = (CustomNode) value;
            append(node.getKey());
        }
    }

the result is other column is editable but first column is not editable

problem 2:

ToolbarDecorator has add remove action but - button is disabled
