The general format for setting up a table is to define a table using "l", "r", or "c" for positioning and vertical bar for column lines. The ampersand & is used to separate items and the "hline" tag for row lines. The code below is used to define the table comparing the advantages of various word processing products:
      \begin{center}
      \begin{tabular}{r|lcc|}\hline
      No. & Formatting Language & Cost & Utility \\ \hline \hline
      1. & HTML & free & fair \\ \hline
      2. & LaTeX & free & good \\ \hline
      3. & Microsoft Word & expensive & good \\ \hline
      4. & vi & free & poor \\ \hline
      5. & Word Perfect 5.1 & cheap & fair \\ \hline
      \end{tabular}
      \end{center}
The actual table looks like the following:
| No. | Formatting Language | Cost | Utility | 
| 1. | HTML | free | fair | 
| 2. | LaTeX | free | good | 
| 3. | Microsoft Word | expensive | good | 
| 4. | vi | free | poor | 
| 5. | Word Perfect 5.1 | cheap | fair | 
Bibliographic references are very handy since LATEX coordinates
any citations in the text to the bibliograph list.  Each bibliography
reference needs to have an identifier such as 
bibitem{RefID}  
reference info
  in the 
bibliography, and then anytime that reference is cited with the
proper 
cite{RefID}, LATEX will handle all
the coordination and numbering of items in the list.
