vue+element动态表头的写法（一）

动态表头的写法有很多种，前端要根据后端返回的数据格式来进行调整。今天给大家展示一种只有值，没有属性的写法

export default {
    props: ['projectId'],
    data(){
        return {
          Header: [],
          bodyData:[],
        }
    },
    methods:{
      saveData(val){
        val.projectId=this.projectId;
        this.$put(`/api/plat/projects/indicDiffReason`,val, function (res) {
          Vue.successMsg("保存成功！");
        })
      },
      getTableData () {
        this.bodyData = []
        this.Header=res.Table.Header
        this.bodyData=res.Table.Rows.map(item=>{
          item.Row=item.Row.map(ele=>{
          //这里因为后端返回的是JSON数据格式，展示的时候我们要取出对象里面的数据
            if(ele && ele.indexOf('{')>-1){
              ele=JSON.parse(ele)
            }
            return ele
          })
          return item
        })
      },
    },
  }
