Text Formatting ⇒ Weird Results in Table using Column Specifications

[Singularity]

Th first table below works fine. In the second talbe, I use column specification, per these instructions, so the column will appear in math mode and get very strange results. Latex moves the double vertical column four columns to the right and no longer prints the first four vertical lines.

Code: Select all

	\begin{tabular}{|r||r|r|r|r|r|r|}
		\hline
		+ & 0 & 1 & 2 & 3 & 4 & 5 \\
		\hline \hline
		0 & 0 & 1 & 2 & 3 & 4 & 5 \\ \hline 
		1 & 1 & 2 & 3 & 4 & 5 & 0 \\ \hline 
		2 & 2 & 3 & 4 & 5 & 0 & 1 \\ \hline 
		3 & 3 & 4 & 5 & 0 & 1 & 2 \\ \hline 
		4 & 4 & 5 & 0 & 1 & 2 & 3 \\ \hline 
		5 & 5 & 0 & 1 & 2 & 3 & 4 \\ \hline 
	\end{tabular}
	\hspace{20mm}
	\begin{tabular}{|>{$}r<{$}||r|r|r|r|r|r|}
		\hline
		+ & 0 & 1 & 2 & 3 & 4 & 5 \\
		\hline \hline
		0 & 0 & 1 & 2 & 3 & 4 & 5 \\ \hline 
		1 & 1 & 2 & 3 & 4 & 5 & 0 \\ \hline 
		2 & 2 & 3 & 4 & 5 & 0 & 1 \\ \hline 
		3 & 3 & 4 & 5 & 0 & 1 & 2 \\ \hline 
		4 & 4 & 5 & 0 & 1 & 2 & 3 \\ \hline 
		5 & 5 & 0 & 1 & 2 & 3 & 4 \\ \hline 
	\end{tabular}

Anyone understand why? How do I fix?
Thanks.

Hi,

obviously you did not load the array package, which is required for this syntax. Insert into your preamble:

Code: Select all

\usepackage{array}

Ahh. Much better.
Thanks.
