It is normal the need to add tables into documents, If you are using LaTeX to write your documents this goal can also be achieved in a very simple way.

We will have to use the tabular environment.

the format for this is:

\begin{tabular}[pos]{table spec}

Where:

pos
Can be eiter:
  • b = bottom
  • c = center
  • t = top
table spec
Can either:
  • l = left-justified column
  • c = centered column
  • r = right-justified column
  • p{width} = paragraph column with text vertically aligned at the top
  • m{width} = paragraph column with text vertically aligned in the middle (requires array package)
  • b{width} = paragraph column with text vertically aligned at the bottom (requires array package)
  • | = vertical line
  • || = double vertical line
With these tools we can start making tables:
\begin{center}
\begin{tabular}{||p{2.5cm}|p{2.5cm}|p{2.5cm}|p{2.5cm}|p{2.5cm}|p{2.5cm}||}
\hline
\textbf{Column 1} & \textbf{Column 2} & \textbf{Column 3} & \textbf{Column 4} & \textbf{Column 5} & \textbf{Column 6} \\ \hline
Linux & is  & a  & great & operating & system \\ \hline
xx & xx & xx & xx & xx & xx \\ \hline
\end{tabular}
\end{center}
This will create a table like this one: Latex Table with Linux screen shot Now explain it a little, first the \begin{center} is centering the table in the document, then we start with the table itself, we declare the environment with \begin{tabular} and the specify the columns we are using p{2.5cm} to specify a column 1 inch wide (2.5 cm), as you can also see we are using double || lines at the left and right and only one | in as columns separators, to draw the horizontal lines we use \hline where we need them. Note that is you do not use p{width} and make a table like this:
\begin{center}
\begin{tabular}{||l|c|c|c|c|r||}
\hline
\textbf{Column 1} & \textbf{Column 2} & \textbf{Column 3} & \textbf{Column 4} & \textbf{Column 5} & \textbf{Column 6} \\ \hline
Linux & is  & a  & great & operating & system \\ \hline
xx & xx & this sentence will never be wrapped and will continue to grow no matter if it extent beyond the paper margins & xx & xx & xx \\ \hline
\end{tabular}
\end{center}
This will be the result: Latex Table with Linux screen shot 2 As you can see the text is never wrapped, therefore it exceeds the paper width. LaTeX tutorial
