我尝试降级到v11.1.0但同样的问题。我的表定义如下所示:
<ngx-datatable
fxFlexFill
#table
class="material striped"
[rows]="rows | async"
[columnMode]="'force'"
[scrollbarV]="true"
[scrollbarH]="true"
[headerHeight]="headerHeight"
[footerHeight]="50"
[rowHeight]="rowHeight"
(scroll)="onScroll($event)"
[selectionType]="'single'"
>

数据是异步的,因此表在 init 上没有数据。有任何想法吗?

您已经定义了“selectionType”,因此您需要在数据表和组件代码中定义“selected”。数据表脚本尝试从所选行中查找 selected.length 或其他相关字段,因此会出现该错误。添加[selected]="selected"到您的模板并添加selected = [];到您的 ts 文件。它必须有效。
