No, it's not. And that is precisely what I spent several hours doing. 
The only method that I could get to work through seaside was #asString. 
So, I thought that there must be some magic that only the experts know 
about. Clicking on the Sort link above my date or time columns returns a 
' Dates are not indexable' error. I inferred from this, that dates could 
not be sorted. Converting them to strings removed the error, which 
re-inforced my belief.

I can see that #sortBlock: assigns an object. But, what does that object 
have to look like to make a WAReportColumn sortable? Something that is 
intuitively obvious for an expert, is frustratingly obtuse to a novice. 
But, you must be getting tired of dealing with novices, so I'm not 
expecting a reply. Thank you. You have been a great help so far.
