PrettyTables.jl v3 changed the API completely. We have to adapt the code to allow it.

[JoshuaLampert]

So now the formatting looks good again, but for some reason PrettyTables.jl prefers to omit some columns instead of creating a scrollbar. I don't know how to fix that.

[SKopecz]

I'd suggest to show tables with less columns. I didn't think much of the scroll bar anyway.

Need to check if three or four schemes fit in one table.

[JoshuaLampert]

Looks good to me. Thanks!

Thanks! I would like to see whether Documenter builds the docs correctly with this commit. The previous build failed for some reason...

[JoshuaLampert]

I think, https://numericalmathematics.github.io/PositiveIntegrators.jl/previews/PR169/convergence/ should display the most recent version in this PR.

[ranocha]

Thanks! I would like to see if Documenter works this time or if there is an issue we need to fix.

Now the docs were built successfully 🥳
