 25    * A low level Table component that generates the rows of the current page in the table.
 26    *
 27    * This component is a variant of {@link org.apache.tapestry.contrib.table.components.TablePages},
 28    * but is designed for operation in a form. The displayed rows are stored in
 29    * hidden form fields, which are then read during a rewind. This ensures that
 30    * the form will rewind in exactly the same was as it was rendered even if the
 31    * TableModel has changed and no StaleLink exceptions will occur.
 32    *
 33    * The component must be wrapped by {@link org.apache.tapestry.contrib.table.components.TableView}.
 34    *
 35    * <p>
 36    * The component iterates over the rows of the current page in the table.
 37    * The rows are wrapped in 'tr' tags by default.
 38    * You can define columns manually within, or
 39    * you can use {@link org.apache.tapestry.contrib.table.components.TableValues}
 40    * to generate the columns automatically.
 41    * <p>
 42    * Please see the Component Reference for details on how to use this component.
