Printing of UndefInitializer()

[bkamins]

Is this intended?

julia> [undef]
1-element Vector{UndefInitializer}:
 UndefInitializer(): array initializer with undefined values

julia> PrettyTables.pretty_table([undef])
┌────────┐
│ Col. 1 │
├────────┤
│ #undef │
└────────┘

The output confuses users as they think the first element of the vector is undefined, while it is defined and is a valid UndefInitializer() value.

Good point! Thanks @bkamins . I will see how can I fix this. The problem is that I am replacing undefined cells with undef internally. I will probably need to create a custom internal variable for this.

Yes - I think custom type should be used.

Ok! This modification is breaking, because if someone is overloading how #undef is shown by default, then it will not work anymore. I will release together with the code I am preparing that adds / modifies what we need to print DataFrames in LaTeX and HTML. My only problem is the unusual amount of work I am getting nowadays 😄 Sorry for the delay, but I am working on it.

[bkamins]

Sure - no rush. This is a minor issue for DataFrames.jl. Thank you for the support!

[bkamins]

bump (just to be sure if it is tracked - thank you!)

[ronisbr]

Yes, it is :) I am struggling with divs in HTML backend... They do not play nice in Jupyter as I thought they will be...

[bkamins]

I know (HTML is hard ...). Thank you!
