I have a JTable extension that has been in use since Java 1.3/1.4 in the project that provided things like column reordering and sorting by clicking on the column. We are upgrading to Java 1.6, and the new JTable stops the old sorting code from working. It would be somewhat extensive rework to fit everything to the new JTable API. Until ...

I know how to implement a wrapping cell renderer, but all popular implementations break when you have multiple wrapping columns. They set row height on demand, but this way one column can override another one's settings. Usually it's de facto the last column what determines row height. E.g. for this data: | Fairly lengthy text | Shorte...
