+    Here is a simple table without column lines:
+
+    \begin{tabular}{ l c r }
+    1 & 2 & 3 \\
+    4 & 5 & 6 \\
+    7 & 8 & 9 \\
+    \end{tabular}
+
+    In this table you get column lines:
+
+    \begin{tabular}{ l | c | r }
+    1 & 2 & 3 \\
+    4 & 5 & 6 \\
+    7 & 8 & 9 \\
+    \end{tabular}
+
+    And of course you can get both:
+    \begin{tabular}{ l | c | r }
+    \hline
+    1 & 2 & 3 \\
+    4 & 5 & 6 \\
+    7 & 8 & 9 \\
