Angular和ng2-smart-table:禁用multi selectmode复选框

我正在使用ng2-smart-table来显示一些数据,我将selectMode设置为“ multi”,以便在左侧具有复选框。在数据中,我有一个对象数组,这些对象带有“ set”属性,该属性是布尔值,可以为true或false,如果set属性为true,如何禁用复选框?有办法吗?

我已经尝试过制作一个新的renderComponent等,但是随后我失去了selectAll功能,而使用renderComponent时,selectRow的工作原理有所不同。

我在顶部放置了一个按钮,该按钮初始化为true,当您按下按钮时,它将禁用所有复选框;

注意:我已经通过点击按钮进行了设置,以便您看到它的实际效果;如果要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ngAfterViewInit()内执行此操作,因为我们必须等待ng2-smart-table被渲染并准备好;我也对此发表了评论;
