Markdown Tables not rendering

[SOLVED] I shouldn't put new line between ---|---|--- and table content :D

I had a similar problem with one of these generated tables on Github Markdown and I found I needed to put a blank line between my header and my table like this:

## Amost always imports

|  R |  Python |    Matlab |
| --------- |:---|:---------|:-----|
| library(tidyverse) |import numpy as np|

Without that blank line the table generation did not happen and those same characters appeared in my Github Markdown instead of the desired table.

May's question and answer led me to the solution, even if her issue was actually a different one, so I am dropping this here - it may help someone else. She got my upvote too...
