+On the average a table will come out okay but you need to keep in mind that when
+(complex) spans are used the results can be less that optimal. However, as
+normally one pays attention to creating tables, the amount of control provided
+often makes it possible to get what you want.
+
+In the following situations, the first cell width is determined by the span. It
+is possible to make a more clever analyzer but we need to keep in mind that in
+the same column there can be entries that span a different amount of columns. Not
+only would that be inefficient but it would also be rather unpredictable unless
+you know exactly what happens deep down. The following two examples demonstrate
+default behaviour.

 Extreme tables can be nested but you need to keep an eye on inheritance here as
 the inner table uses the settings from the encapsulating cell. The widths and
