This is the noted table. The topic was split so that it would not be buried in another post.

Since all of the post are HTML and most of the basic HTML will pass through the Discourse filters unchanged, I created the table by typing in raw HTML. Remember I was coding during the days of punch cards, so there was a time when all HTML was coded by hand and yes I did many HTML pages by hand coding the HTML.
The raw HTML used in this post is

How did I get the HTML code to show as HTML code?
```html HTML code ```
How did I get the Markdown code (```html and ```) to show as markdown code?
<pre>
Markdown code
</pre>
How did I get the <pre> and <\pre> tags to show?
Just bookend the section with ```.
Lets’ just say that I have done it more ways wrong than most people have done it and so now know the right ways.
For a more complicated table that tried to insert SVG images generated using GraphViz DOT see this. As best as I can figure, Discourse does not allow links to images in HTML table cells. So the images should be side by side and not top to bottom.
This is a wiki so that you can click on 
in the lower right of this post and see the raw HTML.
