Time for action – building a table of font family commands

We shall create a table like in the previous example, but this time, we would like to make all entries in a column horizontally centered to each other. We will also add some horizontal lines to mark the border and the header of the table:

1. Create a new document. Define a command for setting the font for the head row:

   \documentclass{article}
   \newcommand{\head}[1]{\textnormal{\textbf{#1}}}
   \begin{document}

2. Begin a tabular environment. As a mandatory argument, provide ccc standing for three centered columns:

   \begin{tabular}{ccc}

3. Write the table head row, write & to separate column entries, and \\ to end rows. Use \hline to insert horizontal lines:

     \hline
     \head{Command} & \head{Declaration} & \head{Output}\\
     \hline

4. Continue with the table body and end the environment and the document. For typesetting LaTeX commands, write \verb|\command|:

     \verb|\textrm| & \verb|\rmfamily| & \rmfamily Example text\\
     \verb|\textsf...
