table, font in table

before the table use '\tiny', then '\normalsize' after the table.

The following are the choices:

\tiny

\scriptsize

\footnotesize

\small

\normalsize

\large

\Large

\LARGE

\huge

\Huge

When we want to change the font on speicified columns in the table:

\usepackage{array}

...

\begin{tabular}{r r r r >{\bf}c >{\bf}r r c c}

or

\begin{tabular}{|c|c|c|c|c|c|c|c|c|c||c|c|>{\bf}c| }

Reminder: don't use $$ on both side of the data.

Use Excel and then Excel2LaTEX is another solution.
