I've got a site with a large table that continuously gets updated with new data - several hundred rows and about ten columns in all. It's mainly text and hyperlinks, and it needs to be able to filter and sort certain columns. Currently I'm using an Excel spreadsheet in an iframe to embed the table into the site, and this gets the job done, but I'm wondering if there's a way to put it directly into the site to allow more formatting flexibility. An HTML table isn't really practical because of how much data there is - is there a better approach to building very large tables that can be edited and updated? Or can anyone recommend a program that is more flexible than Excel? Thanks.
