I think you might be under a mistaken assumption here, because I don't think that this is factual.
The only way I could see your misunderstanding is if you think the quantity of whitespace in markdown tables is important, which it isn't.
This is a working md table and it's not harder to make then the equivalent html version
|Header one|header two|
|---|---|
|Column value 1|column value one|
|value 2|value two|
EtcWherever what's preferable is another story though.
Personally I dislike writing plain html, and would always prefer another template language to generate it, but that's just preference.
Though for the record, you should bee able to escape newlines with a backslash. That admittedly makes the md table into a total disaster, so not suggesting it as an actual option.
Much easier, I'd say.
<table>
<tr>
<th>Header one</th>
<th>header two</th>
</tr>
<tr>
<td>Column value 1</td>
<td>column value one</td>
</tr>
<tr>
<td>value two</td>
<td>value two</td>
</tr>
</table>Also note that you haven't actually done the same as my example.
You're missing <thead> and <tbody>
It's easier to remember the html tags and to see if they are correct.
In markdown I have to remember the weird punctuation and get the | counts exactly correct.
For making something bold, there's low friction in wrapping it in asterisks compared to the HTML version. It's fast, easy and works.
For making a link, the friction is higher because you have to remember the link/text order, and the link/text punctuation. There's a what, one in four chance of getting it right if you haven't memorised it? It always trips me up and I have to go and look it up.
Whereas a link in HTML is pretty much the same format as everything else in HTML.
I think Markdown excels for short or limited things that consist of headings, lists and inline formatting, like blog-posts and comments and ReadMes, but I find it doesn't scale well.
For everybody else, Markdown doesn't save any time, and doing things like creating tables actually wastes time because of the "___" and "|" scaffolding required. Of course you could use a Markdown table generator online but that's just WYSIWIG by another name.
