body: <p>I have a question.
  Libgdx Scrollpane doesnt scroll enough after widgets in the table (that owns a scroll pane) was moved.</p>
  
  <p>Here is the sample from my code.</p>
  
  <pre><code>Table scrollPaneTable = new Table();
  Scrollpane itemsScrollPane = new ScrollPane(scrollPaneTable);
  ...
  mainTable.add(itemsScrollPane).width(WIDTH).height(HEIGHT);
  ...
  //adding items in the scrollPaneTable
  // everything is work perfect at this moment.
  ....
  for (final Actor actor : scrollPaneTable.getChildren()) {
  ...
  actor.moveBy(MAIN_QUEST_ITEM_WIDTH * chapterData.quests.size * direction, 0);
  ...
  }
  ...
  //after I move actor in the table, scrollpane scrolls like before, I can't reach the last items.
  </code></pre>
  
  <p>Thanks for your help.</p>
