bootstrap table字段太長，顯示省略號，鼠標停留顯示文字

{field: 'description',  title: '描述' ,
                formatter : function(value, row, index, field){
                    return "<span style='display: block;overflow: hidden;text-overflow: ellipsis;white-space: nowrap;' title='" + value + "'>" + value + "</span>";
                },
                cellStyle : function(value, row, index, field){
                    return {
                        css: {
                            "white-space": "nowrap",
                            "text-overflow": "ellipsis",
                            "overflow": "hidden",
                            "max-width":"150px"
                        }
                    };
                }
            },
