Does anyone know if it is possible to use boxes in a tabular environment?
E.g. if I have

\begin{tabular}{ccc}
A & B & C \\
D & E & F \\
\end{tabular}

I would like to draw a box around A and B, and around E and F to show that they are grouped together. \fbox{A & B} doesn't work, because fbox ...

thank you gmedina, that was exactly what i was looking for. tikz and the picture environment are too complicated for what i had in mind (and difficult to get right). this solution is much quicker.

Hi guys,

i need to insert a very long arrow in my latex document, almost as long as the width of my text. do you know about a latex command which can do that? i don't mind using an extra package.

I am using beamer for a presentation and I would like to omit the logo from some specific frames. is there a command i can use at the beginning of the frame? I defined the logo by inserting \logo{\includegraphics[width=1.5cm]{mylogo.jpg}} in the preamble.
