Insert row at END of table

I’ve seen several questions about inserting a row in the middle of a table. I simply want to add a row at the end of the table. Is that possible? I triend using Data->Open With… and using Pages, then inserting the row, but that seems to mean I can only open the page in Pages for editing. Does DT3 use a plugin that would allow this?

Please provide more information than this when reporting issues or making inquiries.
