I normally use FireFox, but I just tried this assay on IE and Safari as well, with the same results.

There are values in the data rows. The date fields behave the same way when there are data rows and when I filter all the data out (as I did in the screenshot).

I also just tried making long labels for date fields in a study dataset and a list, and those labels didn't wrap either.

I probably should have mentioned earlier that we are still using Labkey v11.1. Is there any chance this behavior has been fixed since then?

Thanks for your help,
Jen
