Ngx-bootstrap datepicker customClass属性不起作用

Question

我想将类添加到datepicker中的日期。因此，使用customClass属性。

<datepicker ... [customClass]="classList"></datepicker>

this.classList = [{"date":1532111400000,"mode":"day","clazz":"today-class"},{"date":1532025000000,"mode":"day","clazz":"app-calendar-event"},{"date":1532457000000,"mode":"day","clazz":"app-calendar-event"},{"date":1532889000000,"mode":"day","clazz":"app-calendar-event"}]

没有在日期选择器上添加类。
