Ah, ok ... I would like to do someting like this:
1. have a lua table with multiple rows/ columns
2. print that out into a ui element nicely: fixed column width, table headers, autoscrolling, etc
3. read where the user currently has the cursor and highlight that line
4. on key press execute someting based in the current line
As I understand it currently, I would need to write something which does the parsing/ displaying based on newline, tabstops, etc ... so I would basically need to do everything manually.
If I would be using eg HTML/ Javascript, I would just google for it and take one of the many already available libs which deal with taht topic (eg
https://datatables.net/).
My hope was that there already exists a lua lib which has such a functionality ...
