I end up having:

enter image description here

My problems with it are:

  • the diagonal line is too thin
  • the diagonal line does not touch the corners of the cell

Anyone has suggestions on how to achieve what I would like? I already checked here and that's how I found the makecell package and \diaghead, but with poor results, as you can see.

Based in my answer to another question, I had to adapt it here to the longtabu environment.

For this case, there is no need to specify the width of the diagonal cell, because it is pre-computed by tabu. Only the vertical size is neccessary.

Add the following macro definition to your preamble:

\newcommand\diag[4][line cap=round, line width=1.5pt]{%
  % #1 diagonal line style (optional), #2 vertical size of the cell, #3 and #4 labels
  $\vcenter{\begin{tikzpicture}[baseline=0,anchor=south west,inner sep=1pt]
  \path[use as bounding box] (0,0) rectangle (\linewidth,#2);
  \node[minimum width=\linewidth,
        minimum height=#2] (box) {};
  \draw[#1] (box.north west) -- (box.south east);
  \node[anchor=south west] at (box.south west) {#3};
  \node[anchor=north east] at (box.north east) {#4};
 \end{tikzpicture}}$}

And change your line:

\diaghead{\hskip\hsize}{Relative Distance}{Turn Direction}

to

\diag{1.2cm}{Relative Distance}{Turn Direction}

to get this:

Result

Of course you can try different vertical sizes and even change the style of the diagonal, via a first optional parameter:

\diag[thick, gray]{1.2cm}{Relative Distance}{Turn Direction}%

Second result

As you can see, the diagonal does not reach the corners of the cell. This is because tabu always add a padding around the cell contents, and I was unable to find the name of the variables which store those dimensions. However, it does not look so bad currently.

  • thank you! I will test your solution as soon as I get back to the office. I will accept the answer as soon as I can check it. – Federico Nov 15 '13 at 18:34
  • also, might be that the padding is related to this line: \tabulinesep=^1.5mm_1.5mm – Federico Nov 15 '13 at 18:37
