求助：element-plus如何实现动态多级表头？-灵析社区

数据需要自己转下 或者后端就返回那种格式 tableInfo(){ let tableData= [ { area: "NKA_门店1", fullTimeNCs: [ { label: "1个店员评级金额", price: "100" }, { label: "2个店员评级金额", price: "400" }, { label: "3个店员评级金额", price: "600" } ] }, { area: "NKA_门店12", fullTimeNCs: [ { label: "1个店员评级金额", price: "100" }, { label: "2个店员评级金额", price: "400" }, { label: "3个店员评级金额", price: "600" } ] }, { area: "NKA_门店13", fullTimeNCs: [ { label: "1个店员评级金额", price: "100" }, { label: "2个店员评级金额", price: "400" }, { label: "3个店员评级金额", price: "600" } ] } ] let headerList=[] tableData.forEach((item)=>{ item.fullTimeNCs.forEach((citem,cindex)=>{ let key=`customFiled${cindex+1}` item[key]=citem.price; let find=headerList.find(i=>i.label==citem.label) if(!find){ headerList.push({ key, label:citem.label }) } }) }) return { headerList, tableData } }
