Table does not fit

Question

I have put this into LaTeX to get a table in another page:

\afterpage{
\begin{landscape}
\begin{table}[h!]
\begin{center}
\begin{tabular}{| c ||l | l |l | l | l |l | l |l|l |l |l |l | l|l |}
\hline
Interval & \begin{sideways} Unison & Minor 2nd & Major 2nd & Minor 3rd & Major 3rd & Perfect 4th & Diminished 5th & Augmented 4th & Perfect 5th & Minor 6th and Major 6th & Minor 7th & Major 7th & Octave \end{sideways} \\
\hline
Ratios & $\frac{1}{1}$ &  $\frac{256}{243}$ &  $\frac{9}{8}$ &  $\frac{32}{27}$ &  $\frac{81}{64}$ &  $\frac{4}{3}$ &  $\frac{1024}{729}$ &  $\frac{729}{512}$ &  $\frac{3}{2}$ &  $\frac{128}{81}$ &  $\frac{27}{16}$ &  $\frac{16}{9}$ &  $\frac{243}{128}$ &  $\frac{2}{1}$ \\
\hline
Note & C & D\$flat$ & D & E\$flat$ & E & F & G\$flat$ & F$\sharp$& G & A\$flat$ & A & B\$flat$ & B & C \\
\hline
\end{tabular}
\caption{The Pythagorean Chromatic Scale$}
\end{center}
\end{table}

\end{landscape}
}

But I keep getting error messages. Is it because it is too big?!

Answer 1

Such a table is very awkward to read: you have it sideways and the column headers are sideways too.

It's better to transpose it:

\documentclass{article}
\usepackage{booktabs}
\begin{document}

\begin{table}[htp]
\centering

\begin{tabular}{lcc}
\toprule
Interval & Ratio & Note \\
\midrule
Unison & $\frac{1}{1}$ & C \\
\addlinespace
Minor 2nd & $\frac{256}{243}$ & D$\flat$ \\
\addlinespace
Major 2nd & $\frac{9}{8}$ & D \\
\addlinespace
Minor 3rd & $\frac{32}{27}$ & E$\flat$ \\
\addlinespace
Major 3rd & $\frac{81}{64}$ & E \\
\addlinespace
Perfect 4th & $\frac{4}{3}$ & F \\
\addlinespace
Diminished 5th & $\frac{1024}{729}$ & G$\flat$ \\
\addlinespace
Augmented 4th & $\frac{729}{512}$ & F$\sharp$ \\
\addlinespace
Perfect 5th & $\frac{3}{2}$ & G \\
\addlinespace
Minor 6th & $\frac{128}{81}$ & A$\flat$ \\
\addlinespace
Major 6th & $\frac{27}{16}$ & A \\
\addlinespace
Minor 7th & $\frac{16}{9}$ & B$\flat$ \\
\addlinespace
Major 7th & $\frac{243}{128}$ & B \\
\addlinespace
Octave & $\frac{2}{1}$ & C \\
\bottomrule
\end{tabular}

\caption{The Pythagorean Chromatic Scale}
\end{table}

\end{document}

Answer 2

Your code, at least as posted, contains a lot of errors and does not compile. I've tried to clean it up as best I could. Among other things, I've gotten rid of all vertical lines; IMHO vertical lines provide mostly clutter. I've also replaced various \hline instructions with \toprule, \midrule, and \bottomrule, three commands of the booktabs package that produce better spacing. One problem that does not seem to be present, though, is that of the table being too wide to fit into the text block.

\documentclass{article}
\usepackage{graphicx,booktabs}
\newcommand{\rot}[1]{\rotatebox{90}{#1}} % shorthand macro to rotate items by 90 degrees
\begin{document}
\begin{table}
\centering
\begin{tabular}{ @{} l *{14}{c} }
\toprule
Interval & \rot{Unison} & \rot{Minor 2nd} & \rot{Major 2nd} & 
           \rot{Minor 3rd} & \rot{Major 3rd} & \rot{Perfect 4th} & 
           \rot{Diminished 5th} & \rot{Augmented 4th\ } & \rot{Perfect 5th} & 
           \rot{Minor 6th} & \rot{Major 6th} & \rot{Minor 7th} & \rot{Major 7th} & 
           \rot{Octave}  \\
\midrule
Ratio &  $\frac{1}{1}$      &  $\frac{256}{243}$ &  $\frac{9}{8}$ &
         $\frac{32}{27}$    &  $\frac{81}{64}$   &  $\frac{4}{3}$ &
         $\frac{1024}{729}$ &  $\frac{729}{512}$ &  $\frac{3}{2}$ & 
         $\frac{128}{81}$   &  $\frac{27}{16}$   &  $\frac{16}{9}$&
         $\frac{243}{128}$  &  $\frac{2}{1}$ \\[1ex]
Note & C & D$\flat$ & D & E$\flat$ & E & F & G$\flat$ & F$\sharp$& G & A$\flat$ & A & B$\flat$ & B & C \\
\bottomrule
