For a couple years now, I've been using
Araneae as a text editor and HTML editor because it highlights HTML tags. With the release of their new version, it's possible to create custom file types with customized ways of highlighting things. I like this program, because of all I think it has to offer. Therefore, I've taken the liberty of doing an addon with Volition Table files (the skill to do this required nothing more than XML editing...).
The Program (obviously, I didn't write the program, I just added some stuff to the Extensions folder).
Go to the Araneae public download forum. If you find any bugs in the program, go ahead and post them there so that you can help them out.

EDIT: Link edited per request.
The Files Stick all three of these in the Extensions folder found in the main program directory. You should be able to select Volition Table File from File>Document Type.
A screen:

I'd also pimp this program to anybody doing HTML editing...
Again, all I've done is make copies of three files, and then edit them to highlight stuff found in table files.
Known bugs:
@ to : is supposed to be highlighted (for weapons.tbl stuff), but if weapon names have @ in front of them, it highlights the weapon name plus half of the line below it (until it hits a : )
If anybody likes this...enjoy. Took me only a little while to do, but I figured I'd share the wealth.
