docs: update table example to not use commas

[nobkd]

I wanted to use this syntax and noticed, that you have no option to align columns like in the default Markdown syntax:

| #  |       title       |  author  |
|---:|:-----------------:|:---------|
|  0 | name one is long  | auth 1   |
| 11 | name 2            | author 2 |

#	title	author
0	name one is long	auth 1
11	name 2	author 2

Is there support for something like this planned (maybe even for cells)?

Thanks.

I think it should be either that or the Nuemark syntax. Tough decision since the default syntax is too verbose for my taste, but complying to standards is obviously better. Need to think about this.
