Display a collection in a cell?

Im using a CellTable to display my data. But my data has fields that is a collection of string. I wonder if there's any recommendation for this purpose. What do you do in this case?

You have to make a Cell (easiest is to extend AbstractCell as you only have to implement the reder method) that displays your data (i.e. serialize it to HTML).
