# 单个单元格编辑 ElementUi 组件的事件使用

在组件中需配置 column 某项需要编辑先设置属性：canEdit:true
column 中configEdit属性操作可编辑的是输入框/下拉选择/日期选择等:
label: placeholder 显示
editSlotName: 自定义编辑组件作用域插槽方式
editComponent :组件名称可直接指定全局注册的组件（默认是'el-input'），也可引入'element/abtd'如：'a-input/el-input'
bind: 第三方 UI 的 Attributes，如 el-input 中的 clearable 清空功能
event: 触发 handleEvent 事件的标志
eventHandle: 第三方 UI 的事件(第一个参数是本身自带；第二个参数是scope---($index:当前所在行；row:当前行数据；column：当前列数据))
type: 下拉或者复选框显示（select-arr/select-obj）
list: 下拉选择数据源名称
arrLabel: type:select-arr 时对应显示的中文字段
arrKey: type:select-arr 时对应显示的数字字段
