調用Page類的show()方法后，返回的是拼接好的分頁HTML信息。注意到這里提供了theme可供配置，利用theme可以改變返回的HTML信息樣式。
以theme為"%FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END%"為例，返回的是（格式化顯示）：
<div>
<a class="first" href="xxx">xxx</a>
<a class="prev" href="xxx">xxx</a>
<a class="num" href="xxx">xxx</a>
<span class="current" href="xxx">xxx</span>
<a class="next" href="xxx">xxx</a>
<a class="end" href="xxx">xxx</a>
</div>
在看Bootstrap的分頁組件：
<ul class="pagination">
<li>
<a href="#" aria-label="Previous">
<span aria-hidden="true">«</span>
</a>
</li>
<li><a href="#">1</a></li>
<li><a href="#">2</a></li>
<li><a href="#">3</a></li>
<li><a href="#">4</a></li>
<li><a href="#">5</a></li>
<li>
<a href="#" aria-label="Next">
<span aria-hidden="true">»</span>
</a>
</li>
</ul>
可以看出，對於默認分頁組件，只要在外層套上ul.pagination，並將每一項套上li就行。
那么設置theme為：
"<ul class="pagination"><li>%FIRST%</li><li>%UP_PAGE%</li><li>%LINK_PAGE%</li><li>%DOWN_PAGE%</li><li>%END%</li></ul>"
就可以得到返回值（格式化顯示）：
<div>
<ul class="pagination">
<li><a class="first" href="xxx">xxx</a></li>
<li><a class="prev" href="xxx">xxx</a></li>
<li>
<a class="num" href="xxx">xxx</a>
<span class="current" href="xxx">xxx</span>
</li>
<li><a class="next" href="xxx">xxx</a></li>
<li><a class="end" href="xxx">xxx</a></li>
</ul>
</div>
最終效果如圖：
采用配置theme可以不改變源碼的情況下做到bootstrap默認分頁風格。其他風格的需要對源碼進行修改或自定義css風格。
