# Having trouble understanding the tabular environment

Here's my code. I'm trying to generate a five column table with column headings, and a title. Columns centered, with the table completely "lined" by vertical lines only.

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage[]{amsfonts}
\usepackage[]{enumerate}
\graphicspath{ {./images/} }
\usepackage[labelformat=empty]{caption}
\usepackage[margin=1in]{geometry}
\usepackage{array}
\usepackage{amstext}
...
\begin{document}
...
\begin{tabluar}{C|C|C|C|C} % Line 167
\hline
\multicolumn{5}{C}{\text{Dwayne Johnson}} \\
\hline
\text{Dogs} &\text{Cats} & \text{snek} & \text{fish} & \text{Cube} \\ % Line 171
\hline
0.8234578283 & 0.4387443597 & 0.4897643958 & 0.2760250770 & 0.4983640520 \\ % Line 173
0.6948286230 & 0.3815584571 & 0.4455862007 & 0.6797026769 & 0.9597439585 \\

0.9502220488 & 0.7951999011 & 0.7093648309 & 0.1626117352 & 0.5852677510 \\
0.0344460805 & 0.1868726046 & 0.7546866820 & 0.1189976816 & 0.2238119395 \\
\hline
\end{tabular}   % Line 179
...
\end{document}


It's not compiling, and I'm receiving a gamut of errors:

(1) Latex Error: Environment tabular undefined.
(2) Misplaced \omit.
Underfull \hbox (Badness 10000) at paragraphs line 171 -- 172.
(3) Misplaced \noalign.
(4) Misplaced alignment tab character &. Underfull \hbox (Badness 10000) at paragraphs line 173 -- 178.
(*) A few more error (4)'s.
(8) Another \noalign
(9) Misplaced \crcr. Extra }, or forgotten \endgroup. Extra }, or forgotten $. Latex Error: \begin{document} ended by \end{tabular}. Missing$ inserted. Line 179

My code is actually printing the capital C's instead of taking them as a parameter. But it was doing that without the newcolumn macro so I know that's not the issue. Thank you.

• Misspelled tabular. Sorry for wasting everyone's time. But I'm new to LaTex so if you got any tips on mine that would be cool, thank you. Jul 25, 2018 at 23:49
• A matter of taste, but I suggest to have a look at inf.ethz.ch/personal/markusp/teaching/guides/guide-tables.pdf Jul 25, 2018 at 23:53
• @samcarter And in the same vein, but reduced to the essential (and phrased more authoritatively), the ‹booktabs› vignette. Jul 26, 2018 at 6:59

As you have already noted, you have misspelled tabular. In addition, the column specifiers are mentioned as C rather than c. Correcting both, your code compiles fine to yield the table shown.
