Here's a quick example of how I create a box with borders using Latex. I also show how to include a box inside a table. My motivation for this is discussed there also.
Okay, now I'm getting into the crazy LaTeX code. I'm converting HTML UI prototype images into LaTeX so I can include the prototypes in my Requirements Specification docs.
So, that being my motivation, here's some LaTeX example code that shows how to display the equivalent of a textfield inside of a table. At the very least, this demonstrates how to use the LaTeX
fbox command. :)
