没有操作列的正常表格

                    columnDrop() {
                    const wrapperTr = document.querySelector('.el-table__header-wrapper tr')
                    this.sortable = Sortable.create(wrapperTr, {
                        animation: 180,
                        delay: 0,
                        onEnd: evt => {
                        const oldItem = this.dropCol[evt.oldIndex]
                        this.dropCol.splice(evt.oldIndex, 1)
                        this.dropCol.splice(evt.newIndex, 0, oldItem)
                        console.log(this.dropCol)
                        }
                    })
                    },
