你看下我的代码，remote属性是不是正确设置了

//这是我们的jsx
<Table border data={this.list} on-selection-change={this.handleSelectionChange}>
            <TableColumn type="selection" width="120" align="center"></TableColumn>
            <FwTreeColumn label="分类名称" prop="name"
              fileIcon="icon icon-file" folderIcon="icon icon-folder"
              treeKey="id" parentKey="parent_id" allRemote
              remote={this.loadChild}></FwTreeColumn>
            <TableColumn label="操作" scopedSlots={{ default: this.renderOpt }}></TableColumn>
</Table>

//remote指向的加载
  private loadChild(row: Entity, callBack: (data: Entity[]) => void) {
    let child: Entity[] = row.children
    let d = child.map(i => {
      i.parent_id = row.id;
      i.depth = (row.depth || 0) + 1;
      return i;
    })
    callBack(d)
  }

`<el-table-tree-column treeKey="id" expandAll="!!1" parentKey="parent_id" prop="brandName" :remote="remote" width="200px" label="品牌名称"

  >
  <template slot-scope="scope">
    <span>{{scope.row.brandName}}</span>
  </template>
  </el-table-tree-column>`
