Cannot get solid html table borders in jupyter notebook

I am trying to get solid black table borders on my html table in jupyter notebook. I run the following code in a markdown cell:
```

parameter

eenheid

waarde



$RR$

$\text{[-]}$

0.03

```

But now I would like all cells in the table (all td and tr elements) to have their own border. Is there really no other way to do this than adding a `{style="border-style: solid;"}` to each td and tr element?

Adding table borders is really basic functionality. It shouldn't be this hard.

Reproduce the supplied HTML table in a Jupyter Notebook Markdown cell and inspect how its table, row, and cell borders render. Determine whether notebook rendering supports applying the requested solid border to all cells without repeating inline styles; done means the example renders with borders on every cell.
