When providing programming documentation to users of an office suite software, does intelligent cell merging in tables, make the info more accessible?

Examples of such merged-cell use, alongside versions of same info without merged-cell use

Info using merged cells

Same info without using merged cells

Background

I was advised that such merging might make it more difficult for such users to access the information (rather than help them). The adviser also implied that I should ask other programmers of the programming language, what they would prefer in regards to the merging. Because of this, I am posting this question here & at other places.
