I would suggest examining the cell to see if there are any JavaScript events it is raising. You might also try raising various JavaScript events on the cell. Does the cell contain a hyperlink? If so, you might interrogate that and click it instead. You might also need to actually click on the row. I can't recall if that element is exposed in the HTML designer, but you could confirm in interrogation mode by using "Select Element" and selecting the TR tag for a row. If that click works, but not in the HTML table designer, you might need to interrogate the table as you would in the Universal Web Adapter (where you interrogate the Table as a container, the row as a container (with UseKeys enabled), and the cell(s) beneath each row.
