>table with 40k rows

Oh I have one with 6K rows, 300ms to insert into a page if I try to measure, but in reality browser freezes for 3 seconds (1.8s style, 900ms layout, 300ms update tree). Freezing goes away with position: absolute, but it still takes 3 seconds to show up after .appendChild. I tried replacing Table with Flex divs, even worse speed.

If your table is simple (values, no markup), try DataGridXL: here's a One Million Cells Demo that loads in an eyeblink: https://www.datagridxl.com/demos/one-million-cells. (Disclaimer: I am the maker)

Its not real. What good is virtual table if I cant search for contents of last row, "2000;1", after loading the page :( Still, this gives me an idea. Dump contents of my table as text under virtual one so search will at least scroll down to appropriate offsets.

Version 2 (december) will have a very fast search feature. But you're right: CTRL+F does not work, as it is virtual. I don't really understand your idea, can you elaborate?
