And just after I wrote that, I found a way to do it without modify AbstractCellTableBuilder.
The key here is to create a HasCell for each sub row containing the sub row value or an index to find it from the main row value. I made some helper classes for this like ChildCellColumn<https://github.com/nmorel/gwt-celltable-subrows/blob/master/src/main/java/com/github/nmorel/gwt/celltable/subrows/client/celltable/ChildCellColumn.java> . MyDefaultCellTableBuilder<https://github.com/nmorel/gwt-celltable-subrows/blob/master/src/main/java/com/github/nmorel/gwt/celltable/subrows/client/celltable/MyDefaultCellTableBuilder.java> is just a copy of the DefaultCellTableBuilder with a protected scope on style. The custom builder is SubrowTableBuilder<https://github.com/nmorel/gwt-celltable-subrows/blob/master/src/main/java/com/github/nmorel/gwt/celltable/subrows/client/SubrowTableBuilder.java> .
