data(){
  return {
        tableData:[
            {
              ID: "1",
              ClientNO: "000111",
              CloudServiceName: "王小虎",
              Cloudnumber: "2001",
            },
        ];
        olddatas:[],
         input: "", //搜索    
    }

}
某个地方得到表格数据：
this.olddatas = this.tableData; //先赋值给旧数据
    
//点击搜索按钮
    search_btn() {
      let search = this.input;
      let olddatas = this.olddatas;//旧数据
      if (search == "") {
        this.tableData = olddatas
      } else {
        this.tableData = this.tableData.filter(function(item) {
          console.log("过滤", item);
          let searchField = { //我这里把item里面所有字段写进去了
            Cloudnumber: item.Cloudnumber,
            ClientName: item.ClientName,
            CloudServiceName: item.CloudServiceName,
            ID: item.ID,
          };
          return Object.keys(searchField).some(function(key) {
            console.log("key值", key);
            return (
              String(item[key])
                .toLowerCase()
                .indexOf(search) > -1
            );
          });
        });
      }
    },

如果对数据中所有字段都进行排序将searchField换成product
