"table" is an antonym depending upon your location. For Americans, in the context of a discussion, the verb "table" means to set it aside and stop discussing it. For Brits, it means to bring up a topic and discuss it.
That only means "to split". I don't think it can mean "to join together" can it? Unless you mean "cleave to" which is rare and not really the same word.
And if I say I cleaved the halves together, you’d have no chance of thinking that I meant I cut them apart. It’s English, you need context to tell what definition is being used for any word with multiple definitions
> (intransitive, rare) Followed by' to or unto: to adhere, cling, or stick fast to something.
Something can cleave to another thing, but you can't cleave two things together. It's grammatically the same as the word "cling". You can cling to something but you can't cling two things together. It doesn't make sense.
“The mighty sequoia, protected by thick bark and with its foliage typically high above the flames, was once considered nearly inflammable.”

Sure but by now every rational and reasonable reader must understand that whenever they come across the word "inflammable", the author might have misused it and they need to search for additional signals to identify whether it means "inflammable" or "uninflammable". This is not different than how the rational and reasonable reader treats the use of an autoantonym.
