使DataGrid可编辑，你应该添加editor属性到列中。editor告诉DataGrid如何编辑字和如何存储值。我们定义了三个editor：text，combobox，checkbox。 添加编辑功能

function editrow(index){ 
    $('#tt').datagrid('beginEdit', index); 
} 
function deleterow(index){ 
    $.messager.confirm('Confirm','Are you sure?',function(r){ 
        if (r){ 
            $('#tt').datagrid('deleteRow', index); 
        } 
    }); 
} 
function saverow(index){ 
    $('#tt').datagrid('endEdit', index); 
} 
function cancelrow(index){ 
    $('#tt').datagrid('cancelEdit', index); 
}
