Easy setup,configure editable and spreadsheet/table/grid

Hi all,

I have no real clue what I'm doing - I am completely new to this sort of thing. For a few months now I've been trying to find a way to put an editable spreadsheet/table/grid on a drupal webpage. The goal is to keep record of what we have in the pantry at home - so when we're at the supermarket we can use our phones to find out if we have beans or not. Started the project to keep me occupied and also to try to cut back on frivolous spending.

I've looked into sheetnode, slickgrid and a few others - even played around with Alfresco. Can't really get any of them working for me. Either kept giving me cryptic errors/too hard to figure out/couldnt store data....

Required features
- The grid/table/spreadsheet needs to be editable, add/remove columns/rows; fancy in cell images non essential.
- the input data needs to be stored somewhere - ie - the user hits "submit", then if the webpage is refresed his/her changes will still be there.

Anyone done something like this before? Or point me to a good tutorial or manual page for any suitable solution.

Thanks,
Derrick
