I'm new, please bear with me. I know only a bare minimum of html/css/javascript so I've been using the How to Sort a Table tutorial to create a 5-column table I need. And it worked great, up until I hit entries in the hundreds, and then it started slowing down whenever I clicked on the headers to sort the entries. The problem is I need over 2,300 entries on this table, at which point it takes so long to load that the webpage just stops functioning. Is there a better way to sort a large table like this? I looked to javascript because it's the only thing I'm even vaguely familiar with that can do clickable, sortable headers, but if there's something else out there that can do the job then that's what I need to learn.
