This is asked with the mozilla/thunderbird requirement to move away from xul to html5 etc in mind.
XUL did a good job with lists /tables, also with 1000 of lines. For plain html5 etc seems to be a problem.
There is an example written by Ben Bucksch - see here:

- but I would like to have it available using REACT!
Any suggestions for that?
