最近做一个vue前后端分离的项目,前端框架用elementui,在使用el-table的过程中,需要实现行

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>
 <el-dialog class="uiot-dialog"
 width="900px"
 :visible.sync="isShow"
 :before-close="beforeClose"
 :close-on-click-modal="false"
 :title="$t('basicData.device.propDlg.dlgTitle')"
 @open="open">
 <el-table :data="propTableData.col.filter(data => handleAdd || data.name.toLowerCase().includes(handleAdd.toLowerCase()))"
 highlight-current-row
 border>
 <el-table-column label="No."
 type="index"
 align="center"
 width="50"></el-table-column>
 <el-table-column :label="$t('basicData.device.propDlg.code')">
 <template slot-scope="scope">
 <span v-if="scope.row.isSet">
 <el-input size="mini"
 v-model="scope.row.code"></el-input>

 <span v-else>{{ scope.row.code }}</span>
