Datatables with the jEditable plugin.

  Datatables - http://datatables.net/

  jEditable - http://www.appelsiini.net/projects/jeditable

  How to integrate - http://datatables.net/release-datatables/examples/api/editable.html

There is also Dan Bricklin's socialcalc https://github.com/DanBricklin/socialcalc which has some relatively active forks including audreyt's ethercalc https://github.com/audreyt/ethercalc

You can see what the spreadsheets look like at http://www.ethercalc.org/

For just viewing and editing spreadsheets without social features, you can ignore the servers included, the javascript widget works just fine by itself.

Dan Bricklin co-authored VisiCalc, the first spreadsheet program for the masses.

DataTables ( http://datatables.net ) has some overlapping functionality, some of which is provided by plug-ins. For example KeyTable + Editor: http://editor.datatables.net/tutorials/keytable .

DataTables is what we're phasing out in favor of SlickGrid (most likely); it simply croaks when you have 1000's of rows...too many DOM objects in the browser.

Of course, the paged option might alleviate that somewhat, but requirements won't let me use that.

Have you taken a look at the deferred rendering and/or Scroller options for DataTables ( http://tinyurl.com/cr5usea and http://datatables.net/extras/scroller/ )? These can provide a significant speed increase - depending on your data source for the table and how you want to configure the table.

No, but I will now. Thanks!

DataTables is the best single purpose javascript library I have ever used, and I used a ton. I love it.

I've been looking for something like this for a while to provide copy / paste address book import functionality from Excel or any spreadsheet program. Google Apps script was interesting because you could do complex rules like adding validation but I don't think it's really designed to be dropped in to your site to be used by anonymous users and having Google Spreadsheets as a dependency isn't ideal.

However, for simple input this looks great. What else is out there? I saw the projects listed on this project's github but those weren't the same - just start editing and pasting.
