     name: '张三',

    if (search) {
     return this.tableData.filter(dataNews => {
      return Object.keys(dataNews).some(key => {
       return String(dataNews[key]).toLowerCase().indexOf(search) > -1
      })
     })
    }
    return this.tableData
   }
  },
  mounted() {},
  methods: {
   // 筛选变色
   showDate(val) {
    val = val + '';
    if (val.indexOf(this.search) !== -1 && this.search !== '') {
     return val.replace(this.search, '<font color="#409EFF">' + this.search + '</font>')
    } else {
     return val
    }
   }
  }
 }
</script>
