table标签在vue之中可能比较特殊吧~，table标签里面的transition的用法和在table标签中套组件有点相似。
解决办法：

<style>
    .list-enter-active {
      transition: all .3s ease;
    }
    .list-leave-active {
      transition: all .8s cubic-bezier(1.0, 0.5, 0.8, 1.0);
    }
    .list-enter, .list-leave-to
    /* .slide-fade-leave-active for below version 2.1.8 */ {
      transform: translateX(10px);
      opacity: 0;
    }
</style>
<div class="demo">

    <div >点击数字隐藏点击列</div>
    <table>
        <tbody is="transition-group" name="list" >
            <tr key="1"  v-for="(item , index) in list" @click="change(index)" v-show="item.status == 1">
                <td >{{item.number}}</td>
            </tr>
        </tbody>
    </table>
    {{show}}
</div>
<script>
    var vue = new Vue({
          el: '.demo',
          data: {
            list:[{'status':1,'number':2333},{'status':1,'number':6666}],
            show:true,
          },
          methods:{
                change:function(index){
                    this.list[index].status = 2;
                }
          }
        })
</script>
