1、此功能已集成到[TTable组件中]—Vue2TTable组件、Vue3TTable组件

2、最终效果

在这里插入图片描述

3、安装sortablejs

npm install sortablejs --save

4、Vue2实现方式

<template>
 <el-table
      ref="el-table"
      :data="tableData"
      :class="{'cursor':isCopy,'row_sort':isRowSort,'highlightCurrentRow':highlightCurrentRow,'radioStyle':(table.firstColumn&&table.firstColumn.type==='radio'),'treeProps':isShowTreeStyle}"
      v-bind="$attrs"
      v-on="$listeners"
      :highlight-current-row="highlightCurrentRow"
      :border="table.border||isTableBorder"
      :span-method="spanMethod||objectSpanMethod"
      :cell-class-name="cellClassNameFuc"
      @sort-change="soltHandle"
      @row-click="rowClick"
      @cell-dblclick="cellDblclick"
    >
    ....
 	</el-table>
 </template>
 <script>
import Sortable from 'sortablejs'
 props: {
  	// table所需数据
    table: {
      type: Object,
      default: () => {
        return {}
      }
    },
 	// 是否开启行拖拽
    isRowSort: {
      type: Boolean,
      default: false
    }
    ...
},
data() {
    return {
      tableData: this.table?.data
    }
  },
  watch: {
    'table.data': {
      handler(val) {
        this.tableData = val
      },
      deep: true // 深度监听
    }
  },
mounted() {
    this.initSort()
  },
  methods: {
	    // 行拖拽
	    initSort() {
	      if (!this.isRowSort) return
	      const el = this.$refs['el-table'].$el.querySelector('.el-table__body-wrapper > table > tbody')
	      new Sortable(el, {
	        animation: 150, // 动画
	        onEnd: evt => {
	          const curRow = this.tableData.splice(evt.oldIndex, 1)[0]
	          this.tableData.splice(evt.newIndex, 0, curRow)
	          this.$emit('rowSort', this.tableData)
	        }
	      })
	    }
	}
</script>

5、Vue3实现方式

<template>
	<div class="t-table" ref="TTableBox">
	....
	 <el-table
      ref="TTable"
      :data="state.tableData"
      :class="{
        cursor: isCopy,
        row_sort: isRowSort,
        highlightCurrentRow: highlightCurrentRow,
        radioStyle: table.firstColumn && table.firstColumn.type === 'radio',
      }"
      v-bind="$attrs"
      size="default"
      :highlight-current-row="highlightCurrentRow"
      :border="table.border || isTableBorder"
      @cell-dblclick="cellDblclick"
      @row-click="rowClick"
      :cell-class-name="cellClassNameFuc"
    >
    ....
	</el-table>
  </div>
</template>
<script setup lang="ts">
import { computed, ref, watch, useSlots, reactive, onMounted } from 'vue'
import Sortable from 'sortablejs'
const props = defineProps({
 // table所需数据
  table: {
    type: Object,
    default: () => {
      return {}
    },
    required: true,
  },
   // 表头数据
  columns: {
    type: Array,
    default: () => {
      return []
    },
    // required: true
  },
   // 是否开启行拖拽
  isRowSort: {
    type: Boolean,
    default: false,
  }
  ...
})
// 初始化数据
const state = reactive({
  tableData: props.table.data,
  ...
})
// 获取el-table ref
const TTable: any = ref<HTMLElement | null>(null)
// 获取t-table ref
const TTableBox: any = ref<HTMLElement | null>(null)
// 抛出事件
const emits = defineEmits([
  'rowSort',
   ....
])
watch(
  () => props.table.data,
  (val) => {
    // console.log(111, val)
    state.tableData = val
  },
  { deep: true }
)
onMounted(() => {
  initSort()
})
// 行拖拽
const initSort = () => {
  if (!props.isRowSort) return
  const el = TTableBox.value.querySelector('.el-table__body-wrapper tbody')
  // console.log('3333', el)
  Sortable.create(el, {
    animation: 150, // 动画
    onEnd: (evt) => {
      const curRow = state.tableData.splice(evt.oldIndex, 1)[0]
      state.tableData.splice(evt.newIndex, 0, curRow)
      emits('rowSort', state.tableData)
    },
  })
}
</script>
