我无法让GWT生成有效的XHTML。在我们的项目中，我们使用表格布局，因此页面上有很多表格，并且里面有<colgroup>标签以及<col>标签。无论doctype放在主HTML模板中，<col>标记都不会关闭。 XHTML Transitional和XHTML String都已经尝试过。结果是一样的。GWT不呈现封闭的XHTML标记
<table class="header-grid" cellpadding="0" cellspacing="0">
<colgroup>
<col class="header-left">
<col class="header-center">
<col class="header-right">
</colgroup>
<tbody>
...
</tbody>
</table>
<input>元素也没有关闭。我的猜测是，可能有其他未正确关闭的元素，但它们未在应用程序中使用，或者我没有找到它们。
仅供参考。 GWT操作DOM，并且不会以文本方式对内部HTML进行任何插入。它使用JavaScript的appendChild(...)方法以及doc.createElement(...)。
该问题在Chrome，Firefox和IE中均以Web和Dev模式呈现。它发生在未使用UIBinder的页面上。
GWT版本：2.4.0。

该应用程序相当大且复杂，因此在此处显示Java源代码很复杂。我将在这里放置主HTML和gwt.xml文件。 – Vic 2012-08-06 13:26:33
