It suffers from the same defect all html spreadsheets do (even google docs): if you zoom/resize the screen, row/col alignment breaks.

Unbelievable how in this decade it is still almost impossible to make a table work like a spreadsheet in html. How hard would it be to just enforce a couple of css properties in tables to make them behave? Like:

    tbody {overflow:auto;}

    thead,tfoot{position:fixed;}
    tbody td:first-child{position:fixed}

Hello Whatwg, you listening? I know w3c is been deaf for long, that's why I am asking you. Hixie alive? Earth is calling.

* Here is a basic implementation using box model and display:-webkit-box; (chrome/safari in OSX only) http://georgenava.appspot.com/demo/spreadsheetcalc.html

Major props to my friend David for making this. It's a mashup of Handsontable (https://github.com/warpech/jquery-handsontable) and Filepicker.io (https://www.filepicker.io/)

That's a big editable table, not a spreadsheet. But as an editable table, it's nice.

I will say good start but not useful though. Except entering numbers I couldn't do any thing. One good thing is it is very light. The reason people use excel because you can do lot more than just entering numbers.

Why all the negativity?

I personally think the ability to open and save "cloud" spreadsheets was nicely done.

Is this meant to be a Google Docs/Drive competitor?
