I've driven myself into a self-imposed headache. I need to render an HTML table (Elisp representation of it, result of libxml-parse) in ASCII. Org-mode tables are notorious for their lack of support for spanned columns or rows. Yay, table.el can do it, it's nice for inserting a table and modifying the content interactively. However, it's not really suitable for filling out a table programmatically. There's a `table-insert-sequence` command in table.el that allows you to insert text into a selected cell while automatically adjusting the table, but it's agonizingly slow to call as a function. Sadly, table.el doesn't seem to have a function that could "adjust the table" the way how `org-ctrl-c-ctrl-c` does in org-mode (which, again, doesn't support spans).

Like if I have something like this (that's a parsed example from the Wiktionary):

'(table
    ((style . "background-color:#F0F0F0;width:100%")
     (class . "inflection-table"))
    (tbody
     nil
     (tr
      nil
      (th ((colspan . "2") (style . "background-color:#e2e4c0;")) "infinitive") " "
      (td ((colspan . "6") (style . "text-align:center;")) "conocer"))
     (tr
      nil (th ((colspan . "2") (style . "background-color:#e2e4c0;")) "gerundive") " "
      (td
       ((colspan . "6") (style . "text-align:center;"))
       (span
        ((class . "Latn") (lang . "ast"))
        (a ((href . "/wiki/conociendo#Asturian")
            (title . "conociendo"))
           "conociendo")) " "))
     (tr...)
     (tr...)
     (tr...)
     (tr...)))

What's fast and easy way to render it in ASCII?

AFAIK, AsciiDoctor has a very flexible table syntax. So, you may
consider converting the AsciiDoctor format and then using AsciiDoctor
ASCII export.

I think you missed the point that I'm trying to do this in Elisp. This is for a small package I'm writing. I couldn't
find a function anywhere that prints an ASCII table with spans. I thought it would be trivial to write one, turned out
to be a bit trickier than I expected. I'm surprised that something like this doesn't exist already. I'm still hoping
someone already solved that.

In the package manager, for GNU ELPA, NonGNU ELPA, and MELPA,
there are 84 hits for "table" and 16 hits for "ascii", there
is even a package called ascii-table,

  https://github.com/lassik/emacs-ascii-table

Maybe that is what you look for?

I am not sure how far this can go but perhaps you can use shr.el to
render the table with a monospace font (seems to be necessary) with the
table character changed appropriately.  However, as shr inserts space
character with appropriately calculated space display properties, you
need to end up doing post processing to change the display properties
into actual space characters.

This may not be what you want, but is probably related:

Pretty table!

But international phone numbers are written like this

  +49 69 11651

Don't believe me? Just check ITU-T E.123

  https://www.itu.int/rec/T-REC-E.123-200102-I

:)

PS. +44 is the UK BTW, so John is a good example indeed.
    +49 is Germany - Heinrich.

PPS. Again, see if this does what the OP wants:

Interesting.  But I don't see that format there.
I see these instead: +49 691 1651, +49 6 91 16 51.

Maybe the space chars aren't part of the format
specification?

Weird, + (or 00) is the international prefix, 49 is the
country (Germany), 69 is the national destination (Frankfurt)
and 11651 the individual subscriber.

But without the spaces they are just a bunch of numbers
in sequence.

In the UK, the "national destination" can be anything from 2 digits to 4
digits yet all phone numbers are the same length overall (10 digits).

Just fee the `rcd-box-table' how you wish.
