\begin{document}

As usual, this 
\LaTeX \ document contains a bunch of lines
at the beginning which include certain template files, etc.

In order to create a table, we use the usual
``begin'' and ``end'' commands to define a section
of the input file which will go into the table.
The name of this environment is {\bf tabular}.
The {\bf tabular} environment requires that we
immediately provide the basic layout of the table
within a pair of curly brackets.
To specify a table with two columns, put two
letters between the curly brackets, like this:

\begin{verbatim}
\begin{tabular}{l r}
  1  &  222    \\
  33333  &  4  \\
\end{tabular}
\end{verbatim}

The resulting table looks like this:

\begin{tabular}{l r}
  1  &  222    \\
  33333  &  4  \\
\end{tabular}

Inside the {\bf tabular} section,
use ampersand characters \& to separate
the columns, and place a double backslash 
$\backslash \backslash$
at the end of each line.

The letter ``l'' means ``make each element
inside the column left-justified'', 
while ``r'' means ``right-justified'' and
``c'' means ``centered.''
If your table is full of numbers, then probably
right-justified is a good idea; 
if the table is full of text, then perhaps left-justified
is better.

The following table has one left-justified column,
then a centered column,
and finally a right-justified column.

\begin{verbatim}
\begin{tabular}{l c r}
  left for me & centered!  &  this is right  \\
    short     &  sweet     &  terse \\
  avoid verbosity & lots of letters here &  blah blah blah blah  \\
\end{tabular}
\end{verbatim}

\begin{tabular}{l c r}
  left for me & centered!  &  this is right  \\
    short     &  sweet     &  terse \\
  avoid verbosity & lots of letters here &  blah blah blah blah  \\
\end{tabular}

You can get a little fancy by adding horizontal
and vertical lines to your table in a relatively
simple manner:
use vertical bar characters in the ``table setup'' argument,
before or after or between the letters for each column.

\begin{verbatim}
\begin{tabular}{| l | r | }
  1  &  222    \\
  33333  &  4  \\
\end{tabular}
\end{verbatim}


\begin{tabular}{| l | r | }
  1  &  222    \\
  33333  &  4  \\
\end{tabular}


You can add horizontal lines between rows of the table
using the $\backslash{\rm hline}$  command:

\begin{verbatim}
\begin{tabular}{ l  r  }
 \hline
  1  &  222    \\
 \hline
  33333  &  4  \\
 \hline
\end{tabular}
\end{verbatim}


\begin{tabular}{ l  r  }
 \hline
  1  &  222    \\
 \hline
  33333  &  4  \\
 \hline
\end{tabular}


It's often nice to be able to add a title to the
table which spans the entire width, across all the
columns. 
You can use the $\backslash{\rm multiline}$
command to cause one entry to span multiple columns:


\begin{verbatim}
\begin{tabular}{ | l | r | }
 \multicolumn{2}{c}{A two-column title} \\
 \hline
  1  &  222    \\
 \hline
  33333  &  4  \\
 \hline
\end{tabular}
\end{verbatim}



\begin{tabular}{ | l | r | }
 \multicolumn{2}{c}{A two-column title} \\
 \hline
  1  &  222    \\
 \hline
  33333  &  4  \\
 \hline
\end{tabular}
