# Adding Column to Table

\begin{center}
\captionof{table}{Risk Analysis} \label{tab:title}
\begin{tabulary}{0.7\textwidth}{LCL}
Risk      & \ Probability (1-5)  & \ Impact (1-5)  \\
\hline
Software cannot be completed on time. & 2 & 5  \\
System requirements not adequately identified. & 3 & 5 \\
\end{tabulary}
\end{center}


Have a table above, I am trying to create another column called 'Priority (1-5) - ideas on how to do that?

When I add an extra column, LaTeX throws up and says

Extra alignment tab has been changed to \cr. (\end{tabulary} ...)

• Welcome to TeX.SX!. Do some research on how tables work in LaTeX. – Sean Allred Apr 1 '13 at 12:30
• I have done so but I get an 'Extra alignment tab has been changed to \cr. (\end{tabulary} ...) – user1249957 Apr 1 '13 at 12:31
• Well, then I'd edit that into your question. See also the edit to my answer (coming soon to a store near you!) – Sean Allred Apr 1 '13 at 12:37

Since I couldn't find an existing question that dealt with this directly, I'll put this here. I would first suggest taking a look at the LaTeX WikiBook; it is extremely helpful while learning.

Take a look at how things are organized in a LaTeX table:

\begin{center}
\captionof{table}{Risk Analysis} \label{tab:title}
\begin{tabulary}{0.7\textwidth}{LCL}
Risk                   & Probability (1-5) & Impact (1-5)  \\ \hline
Software cannot be ... & 2                 & 5             \\
System requirements... & 3                 & 5             \\
\end{tabulary}
\end{center}


Can you extrapolate? Note: the LCL bit is the alignment (in this case left,center,left) of the columns; adding another column will necessitate another alignment character. The cause of your error arose from the lack of this extra alignment character; LaTeX ran into another column and had no idea what to do with it.

• I can extrapolate the rows but not the columns ;x – user1249957 Apr 1 '13 at 12:36
• @user1249957 see the edit. – Sean Allred Apr 1 '13 at 12:47
• You're very welcome. If it works (and if it's clear why it works), consider accepting it as the answer. – Sean Allred Apr 1 '13 at 12:51
• Trying to extrapolate the columns and it is still struggling ;x – user1249957 Apr 1 '13 at 12:55
• Worked it out, need to change {LCL} brilliant :) – user1249957 Apr 1 '13 at 12:57
