[Tex/LaTex] Table not centering

horizontal alignmenttables

I am trying to center a table but it is not formatting well. I have looked at questions like this but none of the answers there seem to solve my problem.

\documentclass[11pt]{article}
\begin{document}
\begin{center}
\begin{tabular}{ | c | c | c | c | c | c | c | c | c | c | c | c | }
    \hline
    Steps & Trial 1 & Trial 2 & Trial 3 & Trial 4 & Trial 5 & Trial 6 & Trial 7 & Trial 8 & Trial 9 & Trial 10 \\ \hline
    1 & 1 & 1 & -1 & 1 & 1 & 1 & -1 & -1 & -1 & 1 \\
    2 & 0 & 2 & 0 & 0 & 2 & 0 & -2 & -2 & -2 & 0 \\
    3 & 1 & 1 & -1 & 1 & 3 & 1 & -3 & -1 & -3 & 1 \\
    4 & 0 & 0 & -2 & 2 & 4 & 2 & -4 & 0 & -2 & 2 \\
    5 & 1 & -1 & -3 & 1 & 5 & 3 & -5 & 1 & -1 & 3 \\
    6 & 2 & -2 & -2 & 0 & 6 & 4 & -6 & 0 & -2 & 2 \\
    7 & 1 & -1 & -1 & -1 & 5 & 3 & -7 & -1 & -1 & 1 \\
    8 & 2 & 0 & 0 & -2 & 4 & 4 & -8 & -2 & -2 & 0 \\
    9 & 3 & -1 & -1 & -1 & 3 & 5 & -9 & -1 & -1 & 1 \\
    10 & 2 & 0 & -2 & -2 & 2 & 6 & -8 & -2 & 0 & 0 \\
    11 & 3 & -1 & -1 & -3 & 3 & 5 & -7 & -3 & 1 & 1 \\
    12 & 2 & -2 & -2 & -4 & 4 & 4 & -8 & -4 & 2 & 2 \\
    13 & 1 & -3 & -3 & -3 & 3 & 5 & -9 & -3 & 3 & 3 \\
    14 & 2 & -2 & -4 & -2 & 4 & 4 & -10 & -2 & 4 & 2 \\
    15 & 1 & -3 & -3 & -3 & 3 & 3 & -9 & -1 & 3 & 1 \\
    16 & 0 & -2 & -2 & -4 & 4 & 2 & -8 & -2 & 2 & 0 \\
    17 & 1 & -3 & -1 & -5 & 5 & 3 & -9 & -3 & 3 & -1 \\
    18 & 2 & -4 & -2 & -4 & 6 & 2 & -10 & -4 & 2 & -2 \\
    19 & 3 & -3 & -3 & -5 & 7 & 3 & -11 & -5 & 3 & -3 \\
    20 & 2 & -2 & -4 & -4 & 6 & 2 & -10 & -4 & 2 & -2 \\
    21 & 3 & -1 & -5 & -5 & 5 & 1 & -9 & -5 & 3 & -3 \\
    22 & 2 & -2 & -6 & -6 & 6 & 0 & -8 & -4 & 4 & -2 \\
    23 & 1 & -1 & -7 & -7 & 7 & -1 & -9 & -3 & 3 & -3 \\
    24 & 0 & 0 & -6 & -8 & 6 & -2 & -10 & -4 & 4 & -4 \\
    25 & 1 & -1 & -7 & -9 & 7 & -1 & -9 & -3 & 3 & -3 \\
    26 & 0 & -2 & -6 & -10 & 8 & -2 & -10 & -2 & 4 & -2 \\
    27 & 1 & -3 & -7 & -11 & 7 & -1 & -9 & -1 & 5 & -3 \\
    28 & 0 & -2 & -6 & -10 & 6 & 0 & -8 & 0 & 4 & -4 \\
    29 & -1 & -1 & -7 & -11 & 5 & 1 & -7 & -1 & 3 & -3 \\
    30 & 0 & 0 & -8 & -12 & 4 & 2 & -6 & 0 & 2 & -4 \\
\hline
\end{tabular}
\end{center}
\end{document}

I tried a lot of different styles to format this like \centering instead of \begin{center}...\end{center} but none of them work properly.

In the end, the table looks like this

What should I do to fix this issue

You can use package called geometry to solved your table problem

    \documentclass[11pt]{article}
    \usepackage[left=1cm,right=1cm]{geometry}
    \begin{document}
    \begin{center}
    \begin{tabular}{ | c | c | c | c | c | c | c | c | c | c | c | c | }
           \hline
    Steps & Trial 1 & Trial 2 & Trial 3 & Trial 4 & Trial 5 & Trial 6 & Trial 7 & Trial 8 & Trial 9 & Trial 10 \\ \hline
    1 & 1 & 1 & -1 & 1 & 1 & 1 & -1 & -1 & -1 & 1 \\
    2 & 0 & 2 & 0 & 0 & 2 & 0 & -2 & -2 & -2 & 0 \\
    3 & 1 & 1 & -1 & 1 & 3 & 1 & -3 & -1 & -3 & 1 \\
    4 & 0 & 0 & -2 & 2 & 4 & 2 & -4 & 0 & -2 & 2 \\
    5 & 1 & -1 & -3 & 1 & 5 & 3 & -5 & 1 & -1 & 3 \\
    6 & 2 & -2 & -2 & 0 & 6 & 4 & -6 & 0 & -2 & 2 \\
    7 & 1 & -1 & -1 & -1 & 5 & 3 & -7 & -1 & -1 & 1 \\

    \hline
    \end{tabular}
    \end{center}
    \end{document}

[Tex/LaTex] Use column-separator & (ampersand) inside \newenvironment

The problem is that the \begin{...} and \end{...} pair commands automatically create a "group" so that, in effect, the & and \\ are "out of scope" for the tabular, while inside the "production" environment they just show up at a place where the compiler is not expecting them.

A second problem with your definitions is that, even if they would work, they would be adding an extra \\ at the end of the tabular, adding an unwanted space at the end. Perhaps some more appropriate definitions would be

\documentclass[a4paper,10pt]{article}

\newcommand{\production}[1]{#1 ::= &}
\newenvironment{grammar}{\tabular{p{3cm}l}}{\endtabular}

\begin{document}
\begin{grammar}
\production{XmlStartTag} ... \\
\production{XmlOtherTag} ... \\
\production{XmlEndTag} ...
\end{grammar}
\end{document}

Note no \\ at the end of the last production. Also in the definition of the grammar you don't need to repeat the work of \begin/\end, and you can instead directly use \tabular and \endtabular.

[Tex/LaTex] makecell package vertical centering of vertical text

This looks like a bug in the package, so you should contact the author about it. But as a temporary fix, it looks like you can just add the following to your preamble. (Lightly tested.)

\makeatletter
\def\@rothead[#1]#2{\thead{\\[-.65\normalbaselineskip]
  \turn{\cellrotangle}\thead[#1]{#2}\endturn}}
\makeatother

This removes the offending '@' and doesn't seem to have any other ill effects.
