# Table error - black band inside the fields on toprule

I need a help with a table attached in the pictures above. I put this table in a document composed of several chapters. When I compile the single chapter that include the table, i have no error and the table is correctly displayed. When I compile the entire document whit all the chapters, at the page that contains the table, it appears whit a black band that cover the first field on toprule.

I controlled the code and it is the same. I cannot understand what is wrong.

I put the example code below even if the proble seems to be on the entire document

\documentclass{article}

\usepackage{booktabs}
\usepackage[table]{xcolor}

\begin{document}

\begin{table}[]\footnotesize
\caption{\#messaggi scambiati a livello RRC nell'arco di 24h in condizione di standby}
%\label{tab:10}
\centering
\medskip
\begin{tabular}{lr}
\toprule
Messaggio & n. \\
\midrule
\texttt{RRC CONNECTION REQUEST} & 140 \\
\rowcolor{gray!10}
\texttt{SERVICE REQUEST} & 136 \\
\rowcolor{white}
\texttt{RADIO BEARER SETUP} & 109 \\
\rowcolor{gray!10}
\texttt{SIGNALLING CONNECTION RELEASE INDICATION} & 104 \\
\rowcolor{white}
& \\
Totale & 4803 \\
\bottomrule
\end{tabular}
\end{table}

\end{document}

• Hi, hard to tell without any code. The safest way to isolate the cause is to prepare a minimal working example. That gives us code to test and provide a solution. – Johannes_B Mar 24 '14 at 8:48
• I suspect some redefinition with \def or \renewcommand. Did you do something to \heavyrulewidth? – egreg Mar 24 '14 at 9:02
• I entered the code from the table – user21431 Mar 24 '14 at 9:02
• @egreg: No, I have not used redefinitions – user21431 Mar 24 '14 at 9:04
• How do you include the chapters? – Keks Dose Mar 24 '14 at 9:09

OK, this seems to bee the solution: Replace the \rowcolor{} commands with a single \rowcolors{1}{white}{gray!10} for each tabular.
