Graphics, Figures & Tables ⇒ Top border on table does not appear in pdf

[nustorms]

I am working on my masters thesis and have made several tables previously. The one listed below looks fine in DVI, but when I put it into pdf the top line on rows 2-3 does not show up. At first I thought it was a resolution thing, but when I print it out in hardcopy, it is really not there.

Here is the code I am using for my table:

Code: Select all

\begin{table}
\centering \parbox{6in}{\caption{Comparison of features of inertial and satellite navigation systems~\cite{titwest} \label{tab:INSvsSAT}}} \\ \vspace{0.1in}
\begin{tabular}{p{1.5in}|p{1.75in}|p{1.75in}|}
\cline{2-3}

\LCC
 & \lightgray & \lightgray \\
 & Advantages & Disadvantages \rule{0in}{3ex} \\[1ex] \hline
\ECC

\LCC
\lightgray & &\\
\multicolumn{1}{|c|}{\multirow{3}{*}{Inertial navigation systems}} & 
\multicolumn{1}{|p{1.5in}|}{High data rate} & Unbounded errors\rule{0in}{3ex}\\ 
\multicolumn{1}{|p{1.5in}|}{} & Provides translational and rotational data & Knowledge of gravity required \\ 
\multicolumn{1}{|p{1.5in}|}{} & Not able to be jammed or spoofed &  \\ \cline{1-3}
\multicolumn{1}{|c|}{\multirow{3}{*}{Satellite navigation systems}} & 
\multicolumn{1}{|p{1.5in}|}{Errors are bounded} & Low data rate\\
\multicolumn{1}{|p{1.5in}|}{} & & No attitude information \\
\multicolumn{1}{|p{1.5in}|}{} & & Able to be jammed and spoofed \\[1ex] \cline{1-3}
\ECC
\end{tabular}
\end{table}

I have several other tables in my document that work, so any help is greatly appreciated.

Your code is not compilable and so the problem not comprehensible for me because of some unknown commands. Please provide a minimal working example (MWE) that shows the undesired effect.

So after digging through my code some more. The problem is with using colortab and \cline. It looks as though the colortab package overwrites color onto the \cline. Is there a work around for this? This code is as minimal as I can get. It uses packages colortab and multirow.

[...] This code is as minimal as I can get. It uses packages colortab and multirow.

Please follow the link in my last reply and learn what a MWE really is. Afterwards supplement the code you gave to a compilable code example. Don't forget to insert the definitions of commands like \LCC or \ECC which are not provided by the mentioned packages. Otherwise it will be impossible to give specific help.

Alright, let me try this again. The missing piece for the \LCC and \ECC was the \usepackage{pstricks}. Anyways, here is a comilable version of the code. Notice the top line does not appear over the Two upper most cells (Advantages and Disadvantages), if I do not shade the boxes the lines appear, but I want the shading, hence the problem.

Code: Select all

\documentclass[11pt,a4paper,oneside]{report}
\usepackage{multirow}
\usepackage{colortab}
\usepackage{pstricks}

\begin{document}
\begin{table}
\centering \parbox{6in}{\caption{Comparison of features of inertial and satellite navigation systems \label{tab:INSvsSAT}}} \\ \vspace{0.1in}
\begin{tabular}{p{1.5in}|p{1.75in}|p{1.75in}|}\cline{2-3}

\LCC
 & \lightgray & \lightgray \\
 & Advantages & Disadvantages \rule{0in}{2.5ex} \\[1ex] \hline
\ECC
\LCC
\lightgray & &\\
\multicolumn{1}{|c|}{\multirow{3}{*}{Inertial navigation systems}} & 
\multicolumn{1}{|p{1.5in}|}{High data rate} & Unbounded errors\rule{0in}{3ex}\\
\multicolumn{1}{|p{1.5in}|}{} & Provides translational and rotational data & Knowledge of gravity required \\ 
\multicolumn{1}{|p{1.5in}|}{} & Not able to be jammed or spoofed &  \\ \hline
\multicolumn{1}{|c|}{\multirow{3}{*}{Satellite navigation systems}} & 
\multicolumn{1}{|p{1.5in}|}{Errors are bounded} & Low data rate\\
\multicolumn{1}{|p{1.5in}|}{} & & No attitude information \\
\multicolumn{1}{|p{1.5in}|}{} & & Able to be jammed and spoofed \\[1ex] \cline{1-3}
\ECC 
\end{tabular}
\end{table}

\end{document}

This is still not a MWE because it doesn't compile without errors. Please add the definitions of the \ECC and the \LCC command. These commands come neither from the pstricks package nor from the obsolete colortab package. I suggest that you compile this code on your machine to give us a picture of what you have done and attach the resulting output here to your next post. It sure will be possible to get the desired result with up-to-date packages.

At least for the "newest" (1993) version of colortab \LCC and \ECC are defined in line 127:

Code: Select all

\def\LCC#1\\#2\ECC{\CC@{\@preamble}{#1}{#2}}

And the code does compile, giving the described result.
However, I agree with you that the best thing would be to switch to colortbl or xcolor, as suggested by the CTAN description.

[nustorms]

Thanks phi. At least I am not completely losing my mind over here. I will try to use the colortbl package or xcolor to see what happens.

[nustorms]

Just to help anyone that runs into a similar problem. The answer is \hhline, which needs the package of the same name. The problem is with the way \cline works and it shows up with the colortbl package as well. If interested, the attached links can shed some light from someone much smarter than me and interested in broadening people's knowledge [1,2]. Again, phi, thank you for the positive push in the correct direction.

[2] CTAN: package information - hhline

Good day.

I apologize for my bad English.

I have the same problem. The problem partly solved hhline, but hhline{-~-} drew a black line, white line (space) and the black line. White line on a colored background can not be.

Is there something I can do better colors, combining columns, connecting lines, like Excel? As the boxes in the table?
