Is there a "CMS for tables", which allows an admin panel to edit complex HTML tables?
===

My entire project relies heavily on large tables. 

I have two options:

 1. Only edit the content in a CSV file. Write a script which converts the CSV into the HTML I want it to have with the proper classes and ids in the cells. 

 2. Edit the content in the HTML file, which is becoming a nightmare. 

 3. Find a way a quick way to sync Google Spreadsheets data to HTML tables. 

I found this Expression Engine plugin http://pixelandtonic.com/matrix, but I just want to know what else is out there. 

Thanks
