WebGUI 7.6 has a new way to display grids of information, it's called Data Table. You decide how many rows and columns it has, what the column headings are, and then go to town adding in your data.  

From there you can either choose a template that will build a javascript-based dynamic table with full sorting capabilities; Or you can choose to have it output a flat HTML based table. This table is much more powerful and less error prone than the table that you can build using the rich editor. In fact, that's part of the reason we built this one, the one in the rich editor causes more pain than it's worth.

As always, you can test out the new features on beta.webgui.org. The usual caveats apply, this is a beta, so treat it as such. Report bugs if you find them.
