sorry.. I meant I created the elgg database, not the "table" (it was late) and then I created a user with privileges.  The only difference I see on my configuration is that I'm connecting to a remote google cloud instance for my database, not localhost, but I've verified that I can connect successfully from my elgg instance.  I'll take a look at the video just to make sure I'm doing things correctly.. 

I create the table within my within MySql using CREATE DATABASE elgg;

Ok.. so here is information that I believe would be relevant.  I had this same error message appear when I tried to install version 3.1.1 almost 2 months ago.  I never resolved and had to revert to version 2.3.14.  When I followed the instructions on that version, it was a seamless, error-free install.  I wanted to try the latest version because I saw a thread on github: https://github.com/Elgg/Elgg/issues/12809 so it seemed this actually was an issue that was resolved.  But, for some reason that I still can't figure out, it still shows that same error for me.

In more detail it removes all html tables and replaces with collapsible lists, it overrides

Thanks for your work! I'm gonna check it out later. I integrated the datatables plugin in elgg, in a bad way. I might see if I can do what you did here with all tables

I'll probably upload it to the elgg.org plugins section and add some features after I'm confident that it works as intended for others

Do it.

Did you try this one:
