jQuery DataTable - 顶层和固定高度的列级过滤器不能一起工作

I am trying to display data in a jQuery DataTable which has column level filter at the top, fixed height and scroller enabled. I am able to display the column level filter at the top and have it working. But, as soon as I set the height (scrollY property), the column level filters at the top disappear.I am trying to display data in a jQuery DataTab
