写的很好，但是函数循环变个方向啊

    formatter: function (params) {
                        console.log(params)
                        let res = ''
                        for (let i = params.length - 1; i >= 0; i--) {
                            console.log(params[i].name, params[i].seriesName, params[i].value)
                            debugger
                            var data = '<p>' + params[i].name + '</p>'
                            res += '<p class="padding:5px 0;">' + params[i].marker + params[i].seriesName + '<span style="font-weight:900;float:right;padding-left:15px;">' + params[i].value + '</span>' + '</p>'
                        }
                        return data + res
                    }
