I'm having trouble constructing a tabular environment and compiling it with pdflatex. Here's what I'm trying to do:

\documentclass{article} \usepackage[pdftex]{graphicx} \usepackage{caption,tabularx,booktabs} \begin{document} \begin{minipage}{\linewidth} \centering \captionof{table}{Left side FBD} \label{tab:title2} \begin{tabular}{ C C }\toprule[1.5pt] \bf X & \b f Y \\\midrule $0$ & $-F_g$\\ $F_t \sin \theta$ & $F_t \cos \theta$\\ $-F_e$ & $0$\\ \bottomrule[1.25pt] $0$ & $0$\\ \end{tabular} \end{minipage} \end{document}

However, I then get the following error:

! Package array Error: Illegal pream-token (C): `c' used. See the array package documentation for explanation. Type H <return> for immediate help. ... l.8 \begin{tabular}{ C C } \toprule[1.5pt] ! Package array Error: Illegal pream-token (C): `c' used.

I've tried giving each C and argument as I've seen in other source code (I'm still not certain exactly what that argument is for) I get another error message. When I replace C with C{.85in} I now get:

! Package array Error: Illegal pream-token (C): `c' used. See the array package documentation for explanation. Type H <return> for immediate help. ... l.8 \begin{tabular}{ C{.85in} C{.85in} } \toprule[1.5pt] ! Package array Error: Illegal pream-token (.85in): `c' used.

Does anyone know what I'm doing wrong with my tabular? Thanks in advance!

    Use a small c instead of C: \begin{tabular}{ c c } Commented Apr 23, 2013 at 18:59

here is the fixed MWE:

\documentclass{article} \usepackage[pdftex]{graphicx} \usepackage{caption,tabularx,booktabs} \begin{document} \begin{minipage}{\linewidth} \centering \captionof{table}{Left side FBD} \label{tab:title2} \begin{tabular}{ c c }\toprule[1.5pt] \bf X & \b f Y \\\midrule $0$ & $-F_g$\\ $F_t \sin \theta$ & $F_t \cos \theta$\\ $-F_e$ & $0$\\ \bottomrule[1.25pt] $0$ & $0$\\ \end{tabular} \end{minipage} \end{document}

C should be replaced with c

  • Thank you. What is the difference between the lower and upper case c's anyway? Commented Apr 23, 2013 at 19:03

    @David: The difference is the case, and LaTeX (like many programming languages) use a case-specific interface. So, just like you use \sin and not \Sin or \SIN. There is a difference, since LaTeX expects a lowercase l, c, r, p by default. tabularx provides an additional X, while array adds m and allow expansion of the defaults to your liking.
