The person who corrected you could themselves be corrected.
Table = Relation
Row = Tuple
Column = Attribute
Domain = Data Type

I worked for an airline and the word "flight" could be used in three different ways depending on whether you were talking to pilots/attendants, engineers or marketing.
pilots/attendants: a "flight" was out and back from base.
engineers: take and land, could be test, repair, training.
marketing: a six month (on-season/off-season) series of "flights" from/to a given airport.
The spreadsheet analogy is more than good enough for 99.99% of cases, even in reasonably technical speech (unless one is a professor of relational algebra). Does the person who corrected you use the word "whom" correctly? 99.99% of people don't and it really doesn't matter.
