Hello there!
Recently I faced a strange problem with datatables and semantic UI + FixedHeader. When the body has "pushable" (add by semantic UI automatically when the page has sidebar) the FixedHeader is not visible. It is there, I can select it by the chrome developer console "select element" option (screenshot attached) but it is not visible. If I remove the "pushable" manually the header appears (screenshot attached also).
Can anyone help me with this strange behavior?
Thanks!
