javafx - JavaFX8 tree tabel view customize separate cells -

in tree-table-view there child items have in turn other child items. need customize, say, text of cells of pseudo-root items.

is there way assign css class/style items?

update:
ok, got working following cellfactory:

treetblcolumnname.setcellfactory(new callback<treetablecolumn<filemodel, string>, treetablecell<filemodel, string>>() {         @override         public treetablecell<filemodel, string> call(treetablecolumn<filemodel, string> param) {             treetablecell<filemodel, string> cell = new treetablecell<filemodel, string>() {                  @override                 protected void updateitem(string t, boolean bln) {                     super.updateitem(t, bln); //to change body of generated methods, choose tools | templates.                                              system.out.println(this.gettablecolumn().);                     label lbl = new label(t);                     lbl.setstyle("-fx-font-weight: bold; -fx-font-size: 14pt; -fx-text-fill: white;");                     setgraphic(lbl);                  }              };             return cell;         }      }); 

now, how can distinguish between classes? filemodel interface implemented several classes. in cellfactory need know type current cell->item in order apply different styling on it.
thanks.

you can use instanceof:

filemodel filemodel = gettreetablerow().getitem(); if(filemodel instanceof exefilemodel){    //set style here } else if(filemodel instanceof txtfilemodel){    //use style here }
