add the following code to have checkbox column to your tree table

$(function() {

columns:[[  
            {field:'code',title:'Code',width:100,align:'left'},
                {field:'name',title:'Name',width:100,align:'right'},  
                {field:'addr',title:'choose',width:80},  
                {field:'col4',title:'col4',width: 100, 
                    editor: {
                        type: 'checkbox', 
                        options: {on: '1', off: '0'}
                    }, 
                    formatter: function (value, row) { 
                        if (! row.leaf) { 
                            if (value == 1) { 
                                return '<img src="../resources/image/checked.jpg"/>'; 
                            } else { 
                                return '<img src="../resources/image/unchecked.jpg"/>'; 
                            } 
                        } else { 
                            return''; 
                        } 
                    }
