In order to properly format the posts, one needs to use the "markdown code tags" outlined here in the forum welcome page.
This is done to ease the reading of the posts, and (among others) to distinguish the free-form posts' text AND the code/data sample.
E.g. to format data/code samples enclose it in the triple-backticks (```) like so
```
here comes my data sample
```
that will result in (when posted):
here comes my data sample
Read the provide link above to get a better handle on what markdown code tags are and/or what's available.
Thanks for asking for the clarification!
