elementUI中input框无法输入的问题及原因

错误，无法输入

<el-table-column prop="name" label="输入">
        <el-input v-model="input1" placeholder="姓名"></el-input>
</el-table-column>

正确，可以输入

<el-table-column prop="name" label="输入">
        <template slot-scope="scope">
          <el-input v-model="scope.row.name" placeholder="姓名"></el-input>
        </template>
</el-table-column>

猜测是table每行数据不能用全局变量，需指定每一行的变量

完整示例

<template>
  <div id="app">
	<el-table :data="tabletest"  ref="multipleTable">
        <el-table-column prop="name" label="输入">
          <template slot-scope="scope">
            <el-input v-model="scope.row.name" placeholder="姓名"></el-input>
          </template>
		</el-table-column>
    </el-table>
  </div>
</template>

<script>
var inp="";
export default {
	name: 'App',
	data(){
		return{
			tabletest:[{
				name:"hello"
			},{
				name:"vue"
			}
			],
		}
	},
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
