How to properly indicate the AI to format text and what are the available operators?

I could get the AI to embed code snippets, to draw emojis, among other things.
It happened to also generate threads with thread formatting.

Is there a proper way to call formatting features properly?
I am trying to create a character that can use these features, but I'm uncertain how to call them.

Ultimately, if I could do CSS, it would be amazing. This way I could make my "Narrator" character put sub-characters's entries inside of embeds with their own avatars stored on the hard drive. With a background and some fancy formatting with background image even animated avatars. Sky is the limit to that extent. I could refer to pre-existing CSS or have CSS added on the fly in the tags' style="" quotes.

For the moment, I'd like to be able to make it display tables, to define the rows and columns content. In ChatGPT, asking "Tell me Japanese words, give me the romanji equivalent, and the English translation and put it inside of a table" generates a well sorted table with the proper entries where they're needed and the words are correct.

I would imagine that the AI could eventually even integrate imaginary RPG stores and it could use tables to do a lot of things.

Using pre-existing images could allow the creation of imaginary inventories.

Proper maths could keep track of everything.

I'm currently having an RPG adventure with ChatGPT and it can keep track of the adventure and the health and attack points well, and it rolls dices for I and the encountered creatures. IT's amazing.

So... If I want to replicate this locally, I would need that ability to format text properly, knowing every possible formatting operators available in order to keep stuff organised.
