You could use this online generator, or simply use Pandoc to converse LibreOffice Calc documents.
On the other hand creating tables with Markdown Extra isn’t THAT complicated :)
First Header ! Second Header ------------- ! ------------- Content Cell ! Content Cell Content Cell ! Content Cell
But no colspan or rowspan support. See here for more examples on tables in Markdown Extra

* Edit: I thought Reddint won’t parse anything in code blocks. I was wrong. In the example above you need to replace !
with |
.
If you don’t care for the language it’s coded in, try PHP Markdown (supports Markdown Extra) and maybe combine it with HTML Tidy for prettifying.
Have you worked with AJAX yet? Here's something you could do with javascript or php if you haven't tackled AJAX.
Work with a simple API like this one : http://www.timeapi.org/
Build a world clock page with a map or by location if you don't want to waste time dividing up a map. Using jQuery (or other js library), use AJAX to let users change the timezone, move the map.
W/O AJAX, use PHP and Curl to fetch the UTC time from the server (calculate the rest). Would have to pass the current time via a URL parameter (?tz=edt).
Could go to the old stand by of a calculator for javascript. ToDo list is the other often used practice exercise.
If you wanted to do a simple PHP driven site, could look to emulate this simple CMS (it's not a CMS, it was posted as a lark) : https://github.com/volter9/8-cms
Take the basic idea from it and improve it. It's a simple page controller. Maybe set it up so you could do different content types or change what the default content type is.
A possible good avenue to explore if you did this would be to implement PHPMarkdown which is library for converting text to HTML (works like the comments on Reddit). https://michelf.ca/projects/php-markdown/
parsedown is what I use. But there is also php-markdown which has some cool extra features.
I think you missed the bit about Markdown Extensions. Pretty much every Markdown lib is extensible. I don't do PHP, but I've written many Markdown extensions in Python.
