Read row in Numbers on Mac?

Any way to read a row or column in Numbers on Mac?

Here's my situation. I load a large-ish Excel spreadsheet into Numbers, and I have my focus way out at cell AG134 or something like that. Now, I'd like to know the headers for the current column or row.

If this were a Pages spreadsheet, and if I had taken the time to properly set up the row and column headers, there are VoiceOver shortcuts to read those header cells. But it's an Excel spreadsheet and I don't want to bother setting the header row and column, because it's kind of a pain, and because then I'd have to save a second copy in Pages format.

If I just had a command to read current row or column, I could easily get the information I want.

Any suggestions would be appreciated, thanks.
