Is there a single term that can be used to describe both a 'row' and a 'column', such as in a spreadsheet?

EDIT: I like Kris's comment-answer of "linear array", because it doesn't have so much of a loaded meaning as the other answers. Sadly, it's still messy for my use-case: I'm trying to come up with a name for a programming variable that can either hold a row or a column, and 'array' has the wrong meaning in this context.
