<el-popover placement="top" v-model="scope.row.visible">
<p>确定要删除当前内容?</p>
<div style="text-align: right; margin: 0">

<el-button type="primary" size="mini" @click="handleDelete(scope.$index, scope.row), scope.row.visible = false">确定</el-button>
</div>
<el-button
size="mini"
type="danger"
slot="reference">删除</el-button>
</el-popover>
<el-button
size="mini"
type="primary"
@click="handleDefault(scope.$index, scope.row)" v-show="scope.row.defaultValue === 0">默认</el-button>
<el-button

data 部分
col: [
{
label: '值',
prop: 'dataKey'
},
{
label: '显示名',
prop: 'dataValue'
}
],
dropCol: [
{
label: '值',
prop: 'dataKey'
},
{
label: '显示名',
prop: 'dataValue'
}
],
tableData: [],
methos
//行拖拽
rowDrop() {
const tbody = document.querySelector('.el-table__body-wrapper tbody')
const _this = this
Sortable.create(tbody, {
onEnd({ newIndex, oldIndex }) {
const currRow = _this.tableData.splice(oldIndex, 1)[0]
_this.tableData.splice(newIndex, 0, currRow)
}
})
},
//列拖拽
columnDrop() {
const wrapperTr = document.querySelector('.el-table__header-wrapper tr')
this.sortable = Sortable.create(wrapperTr, {
animation: 180,
delay: 0,
onEnd: evt => {
const oldItem = this.dropCol[evt.oldIndex]
this.dropCol.splice(evt.oldIndex, 1)
this.dropCol.splice(evt.newIndex, 0, oldItem)
}
})
},
这样就可以实现基本的行拖拽和列拖拽了
