element 表格拖拽保存插件

这是以前看着一篇文章

1.下载包
npm install sortablejs --save
2.在页面中引入，或者全局引入
import Sortable from ‘sortablejs’
3.在template中

<div id="second"><el-tableclass="threeTable":style="{'height':tableData.length === 0 ? '100px' : 'auto'}":data="tableData"stripestyle="width: 100%;"highlight-current-row:header-cell-style="headerCellStyle"row-key="proCode"><el-table-column type="index" label="序号" width="58"></el-table-column><el-table-column prop="proCode" label="供方编码"></el-table-column><el-table-column prop="proDesc" label="供方名称"></el-table-column><el-table-column label="操作" width="80"><template slot-scope="scope"><el-tooltip class="tree-item" effect="dark" content="删除" placement="top"><el-button type="text" class="" @click="deleteTable(scope.row, scope.$index)"><icon-svg icon-class="iconshanchu" /></el-button></el-tooltip></template></el-table-column></el-table>
</div>

在script中

<script>mounted () {this.rowDrop()},methods: {// 行拖拽rowDrop () {const tbody = document.querySelector('#second .el-table__body-wrapper tbody')const _this = thisSortable.create(tbody, {onEnd ({newIndex, oldIndex}) {const currRow = _this.tableData.splice(oldIndex, 1)[0]_this.tableData.splice(newIndex, 0, currRow) // _this.tableData换成自己的表格即可}})},}
</script>
