vue el-table实现行内编辑功能
＊且听风吟 人气:1最近做一个vue前后端分离的项目，前端框架用element ui，在 使用 el-table 的过程中，需要实现行内编辑，效果大概是这样：
分为下面几个步骤：
（1） 自定义 el-table 的表头（即添加 “新增” 按钮）：
<el-table :data="propTableData.col.filter(data => handleAdd || data.name.toLowerCase().includes(handleAdd.toLowerCase()))" highlight-current-row border> </el-table>
<template slot="header"
slot-scope="scope">
<el-button v-model="handleAdd"
size="mini"
type="success"
round
plain
@click="handleAdd(scope.$index, scope.row)">{{ $t('common.add') }}</el-button>
</template>
表头自定义了一个“添加”按钮，点击 el-table 动态添加一行。
（2） el-table 动态添加一行：
let row = {
code: '',
maxValue: '',
minValue: '',
name: '',
valueType: 'String',
id: '',
typeId: '',
warning: false,
isSet: true
}
this.propTableData.col.push(row)
vue 数据变化驱动 dom 进行更新，给 table 绑定的数据 propTableData.col 添加一个元素，则表格会添加一行。
propTableData.sel 保存当前行数据：
this.propTableData.sel = row
（3） el-table 动态删除一行：
子组件中触发父组件的 delete 事件：
this.$emit('delete', row.id)
（4）当前行状态判断，即是否处于编辑状态，控制表格每一行的按钮元素的移除与插入：
<template slot-scope="scope">
<el-button size="mini"
type="primary"
round
plain
v-if="!scope.row.isSet"
@click="valChange(scope.row,scope.$index,true)">{{ $t('common.edit') }}</el-button>
<el-button size="mini"
type="primary"
round
plain
v-else
@click="valChange(scope.row,scope.$index,true)">{{ $t('common.save') }}</el-button>
<el-button size="mini"
type="danger"
round
plain
v-if="!scope.row.isSet"
@click="handleDelete(scope.$index, scope.row)">{{ $t('common.delete') }}</el-button>
<el-button size="mini"
type="danger"
round
plain
v-else
@click="valChange(scope.row,scope.$index,false)">{{ $t('common.cancel') }}</el-button>
</template>
上面代码中，通过 v-if=“scope.row.isSet” 来判断当前行是否处于编辑状态。
如果当前行处于编辑状态，则按钮为“保存”和“取消”，此时可对当前行进行保存和取消操作，且不能新增，除非先保存当前行；
如果当前行处于非编辑状态，则按钮为“编辑”和“删除”状态，此时可对当前行进行编辑和删除操作。
这样，就可以实现 el-table 行内编辑的需求。
完整版代码如下：
<template>

highlight-current-row
border>
