Hi, Iâm a bit confused because FTDataSource has two methods #cellColumn:row: and #elementAt: with subclassResponsibility. I understand when FTSimpleDataSource implements #elementAt: and uses it in #cellColumn:row:. But as #cellColumn:row: is more general, why is there #elementAt: defined in FTDataSource? Uko
