问题描述

有个项目需求点击添加按钮添加一行，我采用的是自定义表格，刚开始写好之后，点击添加，可以实现，但是却发现输入框不能输入数据，控制台报错

先看一下，错误的代码

这里列出了主要代码

		<el-table :data="tableData" style="width: 98%; margin-left:20px">
            <el-table-column label="属性类型" align="center">
              <el-select v-model="attrType" placeholder="请选择属性类型">
                <el-option label="区域一" value="shanghai" />
                <el-option label="区域二" value="beijing" />
              </el-select>
            </el-table-column>
            <el-table-column label="属性名称" align="center">         
                <el-input v-model="attrName" placeholder="请输入属性名称" clearable />
            </el-table-column>
            <el-table-column label="属性标识" align="center">
              <el-input v-model="attrFlag" placeholder="请输入属性标识" clearable />
            </el-table-column>
            <el-table-column label="属性映射" align="center">
              <el-input v-model="attrMap" placeholder="请输入属性映射" clearable />
            </el-table-column>
            <el-table-column label="属性单位" align="center">
              <el-input v-model="attrUnit" placeholder="请输入属性单位" clearable />
            </el-table-column>
            <el-table-column label="属性符号" align="center">
              <el-input v-model="attrSymbol" placeholder="请输入属性符号" clearable />
            </el-table-column>
            <el-table-column label="操作" align="center">
              <el-button size="mini" type="danger" @click="handleDelete(item, index)">删除</el-button>
            </el-table-column>
          </el-table>

			data () {
			    return {
			      tableData: [
			        {
			          attrType: '',
			          attrName: '',
			          attrFlag: '',
			          attrMap: '',
			          attrUnit: '',
			          attrSymbol: ''
			        }
			      ]
			    }
			  },

实现的效果

看着好像没什么问题，但是inout输入框不能输入东西，控制台报警告，后来仔细看了一下官方提供的自定义数据表格，发现缺少一些代码，

看一下官方的示例

<template>
  <el-table
    :data="tableData"
    style="width: 100%">
    <el-table-column
      label="日期"
      width="180">
      <template slot-scope="scope">
        <i class="el-icon-time"></i>
        <span style="margin-left: 10px">{{ scope.row.date }}</span>
      </template>
    </el-table-column>
    <el-table-column
      label="姓名"
      width="180">
      <template slot-scope="scope">
        <el-popover trigger="hover" placement="top">
          <p>姓名: {{ scope.row.name }}</p>
          <p>住址: {{ scope.row.address }}</p>
          <div slot="reference" class="name-wrapper">
            <el-tag size="medium">{{ scope.row.name }}</el-tag>
          </div>
        </el-popover>
      </template>
    </el-table-column>
    <el-table-column label="操作">
      <template slot-scope="scope">
        <el-button
          size="mini"
          @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
        <el-button
          size="mini"
          type="danger"
          @click="handleDelete(scope.$index, scope.row)">删除</el-button>
      </template>
    </el-table-column>
  </el-table>
</template>
<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-02',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-04',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1517 弄'

        }, {

          name: '王小虎',
          address: '上海市普陀区金沙江路 1516 弄'
        }]
      }
    },
    methods: {
      handleEdit(index, row) {
        console.log(index, row);
      },
      handleDelete(index, row) {
        console.log(index, row);
      }
    }
  }
