Javascript? Forget it.The t:column of the Tomahawk t:dataTable supports the colspan. http://myfaces.apache.org/tomahawk/extDataTable.html http://myfaces.apache.org/tomahawk/column.html

Well, then consider to write a custom component based on the Sun RI. But then you're re-inventing the wheel. Rather talk about it with your project lead. Or ask more specific questions, for example how to install Tomahawk.

It's just free to use? Or are you violating the Apache license somehow?

Well, the best solution turns out to create a custom component.

You can also try to group/render a h:panelGrid in a h:column to simulate multiple columns. This might involve some rework with the layout (CSS should be sufficient tho) and the generated code would look like dirty. But this should work anyhow.
