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. "Axis" isn't bad considering I (purposefully) didn't specify the 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' and 'axis' can give the wrong idea in this context.

I need this term for a logical function name in an assignment for students who aren't programmers.

Is there a single, more generic term that can be used to describe both a row and a column?

In English, we can refer to a line as being horizontal or vertical, but unless we say ‘a line of something’, that implies a one-dimensional line—it doesn't communicate a row or a column of things. So what could we say instead…? A horizontal or vertical _______?

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.
