我正在使用 ng2-smart-table 显示一些数据,我已将 selectMode 设置为“multi”以便在左侧有复选框。在数据中,我有一个带有属性“set”的对象数组,它是一个布尔值,可以是真或假,如果设置属性为真,我如何禁用复选框?有没有办法做到这一点?
我已经尝试过制作一个新的 renderComponent 等,但后来我失去了 selectAll 功能加上 renderComponent selectRow 的工作方式不同。

我在顶部放了一个按钮,初始化为true
,当您按下它时,它将禁用所有复选框;
注意:我已经在单击按钮时设置了它,以便您看到它在运行;如果您想在从父级或默认情况下获取布尔变量后执行此操作,则必须在内部执行此操作ngAfterViewInit()
……因为我们必须等待ng2-smart-table
渲染并准备好;我也在我的 stackblitz 中留下了评论;
