    editor: function (container, options) {
        var dataItem = options.model;           // 当前行记录
        //手工录入为true可修改，否则只读
        if (dataItem.request_only) {
            var $input = $('<input name="' + options.field + '" data-role="comprice" data-min="0" data-decimals="2" onfocus="this.select()"  />');
            $input.appendTo(container);
        }
        else {
            var grid = container.closest(".k-grid").data("kendoSmartGrid");     //SmartGrid
            if (!grid) {
                grid = container.closest(".k-grid").data("kendoGrid");     //Grid
            }
            grid.closeCell();
        }
