              type="text"

              @click="move(scope.$index,scope.row)"
              v-hasPermi="['sourceData:detectManage:remove']"

            <el-button
              size="mini"
              type="text"
              icon="el-icon-bottom"
              @click="upDown(scope.$index,row)"
              v-hasPermi="['sourceData:detectManage:remove']"
              >下移</el-button
            >
 
 
js  通过数组splice 方法进行删除替换从而实现点击上下移动
 
   // 上移
    move(index,row){
     if (index <= 0) {
        this.$message.error('不能继续向上移动')
      } else {
        const upData = this.listData[index - 1]
        this.listData.splice(index - 1, 1)
        this.listData.splice(index, 0, upData)
      }
    },
    // 下移动
     upDown(index, scope) {
      if (index === (this.listData.length - 1)) {
        this.$message.error('不能继续向下移动')
      } else {
        const downData = this.listData[index + 1]
        this.listData.splice(index + 1, 1)
        this.listData.splice(index, 0, downData)
      }
    },
