If you want to put a table to comment, you can create it as code below; the most important thing is the second row, which makes it a table.

Sadly, I never found documentation for it.

| A   | B  | C  | D  |
| --- | --- | --- | --- | 
|  1  |    |    |    |
|  2  |    |    |    |
|  3  |    |    |    |
|  4  |    |    |    |
