As a natural uitable, no. The component supports no features to do that.
All you could do would be to recreate the table with the data transposed and associated column names, etc., as if the data were/are organized that way. But, the uitable would still work/look like a standard one and couldn't interactively add new column with any builtin controls, etc.; they would still be row oriented. To do anything else would require taking over all the keystroke callbacks and rehandling them to recreate a new uitable in place of the existing one to add a column, say...this undoubtedly would be fraught with much pain to get to even work at all and refresh rates and so on likely not good, too,.
All in all, I think not a feasible idea.
