java - TableView: one header with multiple columns -

i trying create table contains column 1 header has several entries per row in javafx 8. result should more or less this:

i tried add subcolumns works perfectly, not able hide headers of subcolums. found solutions hide header older versions of javafx , listview.

also tried add whole listview 1 row, similar suggested jewelsea here: javafx table- how add components?

of course used listview instead of button. tableview presents first entry of listview. here code callback class:

public class ielistviewcallback implements         callback<tablecolumn<connectedielist, connectedielist>, tablecell<connectedielist, connectedielist>> {     @override     public tablecell<connectedielist, connectedielist> call(tablecolumn<connectedielist, connectedielist> param) {         return new tablecell<connectedielist, connectedielist>() {             final listview<string> listview = new listview<string>();             {                 listview.getitems().add("entry 1");                 listview.getitems().add("entry 2");                 listview.getitems().add("entry 3");             }              @override             public void updateitem(final connectedielist connectedielist, boolean empty) {                 super.updateitem(connectedielist, empty);                 setgraphic(listview);             }         };     } } 

of course code testing. entries depend on commited list instead of being hard coded!

you can achieve explicitly setting height of sub-column 0 through css:

column.setstyle("-fx-pref-height: 0;") 

you have sub-columns of column see effect.
