vue -- element表格行列拖拽

element ui 表格没有自带的拖拽排序的功能，只能借助第三方插件Sortablejs来实现,并实现禁止某列被拖拽，用了如下参数handle，filter，preventOnFilter，draggable，配置地址：http://www.sortablejs.com/options.html

 

 

 

 

 

1、npm安装sortable.js 

$ npm install sortablejs --save

2、新建一个公用组件  Sortable.vue

<template>
  <div></div>
</template>

<style>

</style>

<script>
import Sortable from 'sortablejs'
export default {
  data () {
    return {
    }
  },
  props: [
    'tableData', 'dropCol','col'
  ],
  mounted () {
    console.log(this.tableData,this.dropCol);
    this.rowDrop()
    this.columnDrop()
  },
  methods: {
    // 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,
        handle: ".allowDrag",  // 格式为简单css选择器的字符串，使列表单元中符合选择器的元素成为拖动的手柄，只有按住拖动手柄才能使列表单元进行拖动
        filter: ".noDrag",  // 过滤器，不需要进行拖动的元素
        preventOnFilter: true, //  在触发过滤器`filter`的时候调用`event.preventDefault()`
        draggable: ".allowDrag",  // 允许拖拽的项目类名
        onEnd: evt => {
            const oldItem = this.dropCol[evt.oldIndex-1]      -num是多少列被禁止
            this.dropCol.splice(evt.oldIndex-1, 1)
            this.dropCol.splice(evt.newIndex-1, 0, oldItem)
            
        }
      })
    }
  }
}
</script>

3、在需要得页面应用组件

<template>
  <div>
    <sortableJs v-bind:tableData="tableData" v-bind:dropCol="dropCol" v-bind:col="col"></sortableJs>
 <el-table
      ref="multipleTable"
      :data="tableData"
      row-key="id"
      show-summary
      border
      stripe
      height="600"
      row-class-name="tableRow"
      header-row-class-name="tableHeader"
      @row-dblclick="handleSelectionChange"
      style="width: 100%; border-top: 1px solid #c5c5c5"
    >
      <el-table-column type="selection" class-name="noDrag" width="55"> </el-table-column>
      <!-- <el-table-column type="index" label="序号" width="55"> </el-table-column> -->
      <el-table-column
        v-for="(item, index) in col"
        :key="`col_${index}`"
        :prop="dropCol[index].propName"
        :label="item.title"
        class-name="allowDrag"
        width="150"
      >
      </el-table-column>
</el-table>
  </div>
</template>

     col: [
        {
          id: '1',
          title: '序号',
          propName: 'id',
        },
        {
          id: '2',
          title: '时间',
          propName: 'date',
        },
        {
          id: '3',
          title: '地址',
          propName: 'province',
        },
        {
          id: '4',
          title: '星标',
          propName: 'city',
        },
        {
          id: '5',
          title: '主题',
          propName: 'address',
        }
      ],
      dropCol: [
        {
          id: '1',
          title: '序号',
          propName: 'id',
        },
        {
          id: '2',
          title: '时间',
          propName: 'date',
        },
        {
          id: '3',
          title: '地址',
          propName: 'province',
        },
        {
          id: '4',
          title: '星标',
          propName: 'city',
        },
        {
          id: '5',
          title: '主题',
          propName: 'address',
        }
      ],
      tableData: [
        {
          date: '2016-05-02',
          id: '1',
          province: '地址11',
          city: '合作中',
          address: 'A类'
        },
        {
          id: '2',
          date: '2016-05-04',
          province: '地址002',
          city: '未合作',
          address: 'A类'
        },
        {
          id: '3',
          date: '2016-05-01',
          province: '地址11003',
          city: '中断',
          address: 'A类',       
        },
        {
          id: '4',
          date: '2016-05-03',
          province: '地址104',
          city: '未合作',
          address: 'A类',
        },
      ],
