How Can I Hide Rows/Columns in Keynote?

I have a document with roughly 100 rows of non-numerical data. It'd be great to hide 2 or 3 clusters of 10 adjacent rows so I can do a quick visual scan without having to look at all rows in the document.

I'm pretty sure this functionality exists in Excel when you highlight and right-click what you're looking to hide, but in Keynote, all I'm seeing are options to add or delete rows. Similarly, I'm not seeing a menu option for this.

Does the functionality still exist in Keynote, and if so, where? If anyone can help, thanks--it wouldn't be the first time I've overlooked the obvious!
