Thank you @Ronis_BR, super helpful as usual 🫶 Please let me know when the bug is fixed, and I will update the PR accordingly to make styled strings work on all backends.

Make it the default if possible. That way we can rely on the same call for `:text` and `:html`.

Unfortunately we cannot do this because Julia Base use `print` by default to convert objects ☹

Would be possible, from your side, to add `renderer = :show` if the output is HTML?

Another possibility (but it will have some implications) is to always use `show` if a cell is a StyledString.

Maybe I am misunderstanding something. You mean add the option in the test with `sprint`?

My suggestion above was about making the behavior consistent across platforms. For example, I would like to test the new release on Quarto and Jupyter. I am assuming that the default with `print` is enough to make things “work as expected”?

If I `show` a table on the REPL, I get colors. I would like to get the same colors in HTML on Quarto and Jupyter. Please advise on how to achieve that.

No! I mean, pass the option `renderer = :show` to the function `pretty_table`.

Got it. In that case, the option affects the `:text` output in undesired ways. I will add this option for the `:html` output only.

Thanks! Because the other way would require to add StyledStrings.jl as dependency to PrettyTables and always render it using `show`. I am not sure the side effects it will have.

</div>

From what I am seeing, the option removes the colors in the HTML output. I will go ahead and merge the PR to propagate the new release. This `renderer=:show` is the only incosistency between `:text` and `:html` so far.

Yes! Because the bug I mentioned. I just fixed it in `master`. Can you test from `master`? In this case, using `renderer = :show` and StyledStrings.jl will lead to correct colors in HTML backend.

In text backend, any renderer will work correctly.

Gave it a try with the version on master and the color output seems correct in HTML. I only printed it to the REPL with `show` and `MIME"text/html"` though.

Updated the PR with a future 3.0.2 version for PrettyTables.jl. Will rerun tests when the patch becomes available.

Hi @juliohm !

Version 3.0.2 should be out very soon (waiting for the auto merging of the PR).

@Ronis_BR I’ve rerun the tests, and the HTML one is failing on Windows and Ubuntu with Julia LTS. Any idea of what might be happening?

Yes! It is related to how StyledStrings.jl renders to HTML. You can see the difference between the header in one side of the test:

```julia-auto
      <th style = \"text-align: center; font-weight: bold;\"><pre><span style=\"font-weight: 700;color: #803d9b;\">a</span></pre></th>

```

To the other:

```julia-auto
      <th style = \"text-align: center; font-weight: bold;\"><span style=\"font-weight: 700; color: #803d9b\">a</span></th>

```

Notice that in the former we have `<pre>`.

I remember some discussion about it and having `<pre>` is just wrong here. Hence, it was probably fixed but not ported to LTS.

I dont know what to do in this case because the tests are passing in MacOS with Julia LTS.

Should StyledStrings.jl release a patch to fix the issue on Linux and Windows?

I have absolutely no idea! I cannot understand why the change was applied to LTS in macOS and not in Windows and Linux.

@Ronis_BR I’ve commented out that test temporarily and created a new release.

Looking forward to that. DataFrames.jl is locking further updates.

> Finally, I’ve completed the first release of [PrettyTables.jl](https://juliaregistries.github.io/General/packages/redirect_to_repo/PrettyTables) version 3! For anyone using this package, **we can assume that everything in the API has changed (sorry about that :D)**.

Great to hear of all the improvements!

But, for those of us that were happily depending on v2, is there any sort of migration guidance? Starting from the top of the docs and trying to recall and compare with the previous API for each use-case is not a process I would enjoy much. Knowing what things I need to pay attention to would dramatically improve my likelihood of actually transitioning from v2 to v3.

How about have the author provide one PDF document in version 2 and one PDF document in version 3. Send both documents to the LLM simultaneously and have the LLM migrate them for you?

Thanks @tchr ! That would be great but, unfortunately, I will have no time to create such a document. Nevertheless, usually the calls to `pretty_table` are simple. Thus, the migration should be quite easy by looking at the documentation. If you have any problems, fell free to ping me here!
