# Change LaTeX Margins with Package geometry

http://web.image.ufl.edu/help/latex/margins.shtml

Changing the spacing on a document-wide basis is done for different document settings using different packages. The geometry package controls the overall margins and text area of the document. The package must be called in the preamble of the document and specified when called.

The geometry package is called with the use package command, followed by the options, and then the package name, like this:
usepackage[left=2cm,top=1cm,right=3cm,nohead,nofoot]{geometry}

# LaTex tables with rotated column labels

Trying to get a huge correlation table into a readable pdf document using LaTeX i have to rotate the column lables since the variable names differ a lot in lenght. Dr. Andrew J. Page posted this solution on his blog:

The LaTeX package rotating is needed so include
\usepackage{rotating}
in the preample of the document.

Every single column label has to be included into
\begin{sideways}MyColumnLabel\end{sideways}
Thats a bit awkward, but thats the way it is….

An example from the blogpost mentioned above:
\begin{tabular}{rr} \hline \begin{sideways}Paper\end{sideways} &\begin{sideways}Static\end{sideways} \\ \hline HAR1994j & Journal \\ SWRT1996c & Conference \\ \hline \end{tabular}
