Interlinear Text Layout (Table?) and User Interaction

[creative-resort]

Hello everyone :) I hope this is a good place to discuss
a Use Case I'm scratching my head about, wondering how to best implement it:

• It is interlinear text — basically multi-line text where each line is made of multiple rows
  with connected versions (e.g. languages) of words sitting in it, that are aligned with the words they belong to.
• One could also describe it as "tabular" multiline text,
  the line being a long table with wrapping capability at the end of the line.

Rendering it as multiple adjacent tables
while internally keeping the data in a contiguous datastructure may work

One would also need to consider: How would selection of text work?
Users may want to:

• select only particular rows across multiple interlinear lines
• select only a certain span of columns/words of all rows
• ... or of a selection of rows

"Export to clipboard" would need to be possible in:

• tabular form, representing the layout on screen in plain text
• as one long table (see the above example, where only one column is wrapped and would better go to the same "line" with the rest)

For responsive design, the resulting tables' HTML would need to be recalculated upon resizing, to simulate true multiline wrap behaviour.

To my knowledge, such an editor feature / widget doesn't yet exist anywhere.
Using CKEditor 5, how would you approach this challenge?
Do you see further aspects, that would need to be covered, which I haven't yet been able to think of?
