JavaFX 8中的WebKit版本是什么？

我想将JSTestDriver与jenkins-CI集成.问题是构建服务器没有显示.有没有办法无头地运行浏览器？

谢谢

我想在 Wildfly 服务器上部署一个 Web 应用程序 (app.war)。Web 应用程序有自己的自定义安全管理器集，不允许更改 Java 安全策略。我能够成功部署 Web 应用程序。但是访问它时，它抛出以下异常。有没有办法在不更改应用程序代码的情况下解决问题

我有一个html表,如下所示

<table class="report">
    <tbody>
      <tr>
        <td >col1</td>
        <td >col2</td>
        <td>col3</td>
        <td >&nbsp;</td>
        <td >&nbsp;</td>
        <td >&nbsp;</td>
        <td >&nbsp;</td>
      </tr>
      <tr>
        <td>R2</td>
        <td >2/17</td>
        <td >{2/17}</td>
        <td >&nbsp;</td>
        <td >&nbsp;</td>
        <td >&nbsp;</td>
        <td >&nbsp;</td>
      </tr>
    </tbody>
</table>

如您所见,在col3之后,所有后续列都为空.我只想显示前三列并隐藏其余列.我怎样才能使用CSS实现这一目标.我没有控制HTML表,所以我无法修改它.

谢谢
