Live Edit Tables?

Hey all,

I have several tables which will need to be edited often every week - and rather than update the html and uploading again. I am looking for a option to edit it live from the website. I know there are several options out there that do this but I am just wondering if the following is possible?

I want a login on my website which I will only know the password.
Once logged in I want the table to be changed to (editable status).
Make the change and when I log out I want it to be saved and back to (non editable status) for public viewing.

Is this possible or does any body know of any products/source code that is possible to do this? Possibly jquery or through ajax or ruby or something??

Thanks in advance!!
