Spreadsheet and Tables???

Does anyone know of a plug-in that would function and look similar to Excel spreadsheet? I have recently found a similar extension called “jquery spreadsheet” which to my understanding is included in “tiki”. However, I am used to navigating and utilizing “wordpress”, that any attempts to set-up, navigate, and create a site with “tiki” is confusing and not user friendly by any means. I would like to stick with “wordpress”, but really need the functionality of Excel for the end-users to be able to input data, save, edit, and/or other.

I have heard about “WP-Table Reloaded”. Does anyone know if this plug-in would address my needs? Any help regarding this matter is appreciated. Thanks.

Example:

I need an online spreadsheet that can do the following:

1. End-users are able to input data of daily activities (similar to a log of their activities; who did what, where, when, how, frequency…

2. Data is stored and can only be modified, changed, deleted, and/or other by admin

Thanks.
