[bug-fix] Add padding to default markdown table cells (#2617)

Default, meaning `pretty_table: false`

## Sample code

```md
|   First Column   |  Second Column  |  Third Column  |
|------------------|-----------------|----------------|
| Sed in.          | Sed non.        | Morbi egestas. |
| Donec facilisis. | Suspendisse eu. | Nulla porta.   |
| Praesent a.      | Interdum et.    | Sed nec.       |
```
