Vue实现table上下移动功能示例

<el-table :data="tableList">
</el-table>

<el-button icon="el-icon-arrow-up" :disabled="scope.$index === 0" @click="upFieldOrder(scope.$index)"></el-button>
<el-button icon="el-icon-arrow-down" :disabled="scope.$index === tableList.length - 1" @click="downFieldOrder(scope.$index)"></el-button>

upFieldOrder (index) {
  let temp = this.tableList[index-1];
  this.tableList[index-1] = this.tableList[index]
  this.tableList[index] = temp
 },

upFieldOrder (index) {
  let temp = this.tableList[index-1];
  Vue.set(this.tableList, index-1, this.tableList[index])
  Vue.set(this.tableList, index, temp)
 },

downFieldOrder (index) {
  let i = this.tableList[index+1];
  Vue.set(this.tableList, index+1, this.tableList[index])
  Vue.set(this.tableList, index, i)
 }

destroyed() {
 let param = {
  infos: []
 }
 this.tableList.forEach((dataItem,index) => {
  param.infos.push({
  参数1: dataItem.值1,
  参数1: dataItem.值2,
  参数顺序: index
  })
 });
 // 调用后台，并传入 param
 changeTableOrder(param).then(res => {
  if(res.success=== true) {
 alert('顺序调整成功')
  }
 })
 }
