Hi Brian, I could comment on how to pass the indices, but instead I'd like to recommend using https://github.com/openfin/fin-hypergrid
Here is a demo http://openfin.github.io/fin-hypergrid/ I built a spreadsheet app with it using MicroJ some time ago. It had no issue dealing with 1 million+ rows. I could update it for standard J. fin-hypergrid also has some K support https://openfin.co/2015/01/05/introducing-hypergrid-will-blow-mind/ Joe On Thu, Nov 10, 2016 at 8:37 AM, Brian Schott <[email protected]> wrote: > The jsfiddle example below shows how to use jQuery to make a spreadsheet > style rectangular selection.
