+ *  File:         demo_table.css

+ * ***************************************************************************
+ * DESCRIPTION
+ *
+ * The styles given here are suitable for the demos that are used with the standard DataTables
+ * distribution (see www.datatables.net). You will most likely wish to modify these styles to
+ * meet the layout requirements of your site.
+ *
+ * Common issues:
+ *   'full_numbers' pagination - I use an extra selector on the body tag to ensure that there is
+ *     no conflict between the two pagination types. If you want to use full_numbers pagination
+ *     ensure that you either have "example_alt_pagination" as a body class name, or better yet,
+ *     modify that selector.
+ *   Note that the path used for Images is relative. All images are by default located in
+ *     ../images/ - relative to this CSS file.

+ * DESCRIPTION
+ *
+ * The styles given here are suitable for the demos that are used with the standard DataTables
+ * distribution (see www.datatables.net). You will most likely wish to modify these styles to
+ * meet the layout requirements of your site.
+ *
+ * Common issues:
+ *   'full_numbers' pagination - I use an extra selector on the body tag to ensure that there is
+ *     no conflict between the two pagination types. If you want to use full_numbers pagination
+ *     ensure that you either have "example_alt_pagination" as a body class name, or better yet,
+ *     modify that selector.
+ *   Note that the path used for Images is relative. All images are by default located in
+ *     ../images/ - relative to this CSS file.
