When using the datapaginator with vertical setting, the buttons forward, fast-forward and last are rendered in the same row of the page facets.

I don't know if the problem has been already fixed, but here there is my fix in the DataPaginatorRenderer:

    protected void renderScroller(FacesContext facesContext, UIComponent uiComponent) throws IOException {

          ....

            Element td = domContext.createElement(HTML.TD_ELEM);
            tr.appendChild(td);
            Element paginatorTable = domContext.createElement(HTML.TABLE_ELEM);
            td.appendChild(paginatorTable);
            renderPaginator(facesContext, uiComponent, paginatorTable,
                            domContext);
        }
        
        // FIX BUG for vertical setting
        // Horizontal shares a table row, but for vertical,
        // have them each auto-create their own table row
        if (scroller.isVertical()) {
            tr = null;
        }

        handleFacet(facesContext, scroller, domContext, table, tr,
                    scrollButtonCellClass, scroller.getNext(),
                    DataPaginator.FACET_NEXT);
        
        ....

    }
