我看了一下,报错是我这边的代码报的,但报错的原因是因为视图显示错乱了.
我需要一个只能在同级之间拖动排序的表格.但如果将拥有子集的行展开,可以将与它同级的另一行拖动到已展开的行下,视图上作为它的子级存在.但是数据上好像并没有问题.

拖动前

拖动后

onMove(evt, originEvt, { dragged, related }) {
      if (dragged.parent === related.parent) {
        return true
      }
      return false
},

    orderMove(evt, originEvt, { dragged, related }) {
      if (dragged.parent === related.parent) {
        if (related.parent.level === -1) {
          this.$refs.table.toggleRowExpansion(related.data[related.index], false)
        }
        return true
      }
      return false
    },

这样可以简单的解决问题,但是并不好用
