private void saveColumnWidths() {
    JavaFXUtils.runLater(() -> {
        if (preferenceKeyFactory.get() != null) {
            final double[] columnWidths = tableView.getColumns().filtered(TableColumnBase::isVisible).stream().mapToDouble(value -> Math.floor(value.getWidth())).toArray();
            final Preferences preferences = Preferences.userRoot().node(preferencesUserRoot + PREF_NODE_REG_WIDTH);
            preferences.put(preferenceKeyFactory.get().get(), EncodeDecode.encodeDoubleArray(columnWidths));
        }
    });
