Jupyter-book: Tables are not rendered

[henryiii]

Describe the bug

A markdown table, rendered in Jupyter, does not get rendered in the jupyter-book output.

| Quantity            | Name               | Unit|
| ------------------ :| ----------------- :| -- :|
|  Length             |  millimeter        | mm  |
|  Time               |  nanosecond        | ns  |
|  Energy             |  Mega electron Volt| MeV |
|  Positron charge    |  eplus             |     |
|  Temperature        |  kelvin            | K   |
|  Amount of substance|  mole              | mol |
|  Luminous intensity |  candela           | cd  |
| Plane angle         |  radian            | rad |
|  Solid angle        |  steradian         | sr  |

Gets rendered as this:

| Quantity | Name | Unit|
| ------------------ :| ----------------- :| -- :|
| Length | millimeter | mm |
| Time | nanosecond | ns |
| Energy | Mega electron Volt| MeV |
| Positron charge | eplus | |
| Temperature | kelvin | K |
| Amount of substance| mole | mol |
| Luminous intensity | candela | cd |
| Plane angle | radian | rad |
| Solid angle | steradian | sr |

$ jupyter book build mybook
ERROR ...

I should have a live example at some point soon, my GitHub-actions is broken (jupyter-book + conda worked beautifully, pushing to GitHub is not working)

PS: You can type juptyer book instead of jupyter-book; just like git does, the Jupyter command delegates to programs with dashes in the path. Might be more memorable for users, don't know. :)

Oh, just noticed the extra spaces there that make it a non-normal markdown table. Will try making it a normal markdown table then see. It would then just be a case where the renderer is pickier, which is not as bad.

Hmmm - tables should work just fine. We are using this parser for our markdown: https://myst-parser.readthedocs.io/en/latest/using/syntax.html?highlight=table#extended-block-tokens

which lists tables in that page

[henryiii]

Yep, an "invalid" table (with spaces like this -- : instead of --:) works in Jupyter lab, but not in Jupyter book. It's an oddity, but not bad; the correct fix is to fix the table. Then it works fine.

[henryiii]

Unless you have other thoughts, I think this can be closed. Takeaway, the parser is a little picker than the Jupyter lab parser.

[henryiii]

Note: the GitHub parser does't allow tables with spaces like that either, which is how I noticed. :)

that's good to know - thanks for the clarification
