I have been making progress - I think that the problem was that I entered incorrect values in the columns setting sorting table. Things are working better but not perfectly. Now when I select ARI Data Table I get the double header and footers to the table as shown in the attached jpeg. Note that one pair of them is correct and functional and the other isn't. Any ideas?
Also, the initial display only has 10 items in it even though I set the field Number of Rows to Display to 20.
Anyway, as I said I'm making progress so that's good
