2、element最简单方法：加入以下2属性 即可,row-key为返回数据的唯一标识字段

更正：否则报异常

 

 3、移除同步：

 //删除步骤

    stepDelte(item){

      if(!item){

      return;

      }

      const that = this

      let ids=[];

      let list=[];

      let removeObj=[];

      if(that.selectUserData && that.selectUserData.length>0){

        for(let i=0;i<that.selectUserData.length;i++){

          if(that.selectUserData[i].Id == item.Id){

            //删除table的选中行

           removeObj.push(that.selectUserData[i]);

            continue;

          }

          ids.push(that.selectUserData[i].Id);

          list.push(that.selectUserData[i]);

        }

      }   

      if(removeObj.length>0){

        for(var i=0;i<removeObj.length;i++){

          //删除table的选中行  

           for(let j=0;j<that.selectUserData.length;j++){

              if(that.selectUserData[j].Id == removeObj[i].Id){

                 that.$refs.usersTable.toggleRowSelection(that.selectUserData[j],false);

              }

           }

        }

      } 

      if(list.length < 1){

        //全部删除table的选中行

        that.$refs.usersTable.clearSelection();

      }

      that.selectUserData = list;

      that.modelFormWating.WatingUserIds='';

      if(ids.length>0){

        let idList= ids.join(',');

        that.modelFormWating.WatingUserIds=idList;

      }

    },
