Extra alignment tab with longtable

Question

I am using longtable and I am getting the error ! Extra alignment tab has been changed to \cr. I have attempted to fix it but nothing I have tried seems to be working. Below is the code for the table

  \centering
    \begin{longtable}{rrrrrrrrrrrrrrrrp{2cm}}
    \caption{A Table Depicting the Relationship between Meat, Fruit, Oil}
   Oil (Barrels) & Fruit (Ton) && Meat (Ton) & Fruit (Ton) && Meat (Ton) & Oil (Barrel) & Oil (Barrels) & Fruit (Ton) & & Meat (ton)  & Fruit (ton) &       & Meat (ton)  & Oil (barrel)  \\

You should rather use something like *{16}{r}, instead of rrrrrrrrrrrrrrrr. — Werner, Mar 21 '13 at 21:36
The problem here is \caption inside longtable. Move it outside of the longtable environment. Why do you need a longtable for this not-so-long table? — Werner, Mar 21 '13 at 21:38
@Werner I replaced what you provided and now I get ! LaTeX Error: Illegal character in array arg. — Jeel Shah, Mar 21 '13 at 21:38
@egreg: Ahhh, right, but it's still the problem. From the longtable documentation: "The \caption{...} command is essentially equivalent to \multicolumn{n}{c}{\parbox{\LTcapwidth}{...}}." — Werner, Mar 21 '13 at 21:40

you forgot the double backslash after the \caption{...}\\

It is like a multicolumn an own line in a tabular.

Here is only an idea to get it smaller:

\documentclass[parskip=half]{scrartcl}
\usepackage{longtable,graphicx}
\def\RB#1{\rotatebox{90}{#1}}
\begin{document}

\begin{table}[!htb]
 \caption{A Table Depicting the Relationship between Meat, Fruit, Oil}

\resizebox{\linewidth}{!}{\tabcolsep=2pt%
 \begin{tabular}{*{16}r p{2cm}}
  \RB{Oil (Barrels)} & \RB{Fruit (Ton)} && \RB{Meat (Ton)} & \RB{Fruit (Ton)} && \RB{Meat (Ton)} & \RB{Oil (Barrel)} & \RB{Oil (Barrels)} & \RB{Fruit (Ton)} & & \RB{Meat (ton)}  & \RB{Fruit (ton)} &       & \RB{Meat (ton)}  & \RB{Oil (barrel)}  \\

I have done that and now the error goes away but the table isn't wrapping to the next page, how can I fix that? I thought longtable automatically wrapped the table to the next page? — Jeel Shah, Mar 21 '13 at 21:42
@gekkostate: longtable does it, but only in the vertical direction -> tabular lines. But not for columns! That can only be done by ConTeXt. — , Mar 21 '13 at 21:44
How can that be done? or Am I just better off splitting the table into two? — Jeel Shah, Mar 21 '13 at 21:45
@gekkostate: It can be done when using ConTeXt instead of LaTeX. I suppose you should rotate your tabular. — , Mar 21 '13 at 21:46
I am looking at the wiki book for LaTeX and it recommends the tabu environment. What is your opinion? — Jeel Shah, Mar 21 '13 at 21:54
@gekkostate Oh you want to split vertically There is a an answer for that I'll find it — David Carlisle, Mar 21 '13 at 22:01

You need \\ (or \endhead) after \caption{}

@Herbert yes perhaps, I just added something as the system complained I was under 30 characters:-) – David Carlisle Mar 21 '13 at 21:49
yes, 30 is too big for short answers :-) – Mar 21 '13 at 21:51
