/**

25 |
* A low level Table component that generates the columns in the current row in the table. This

26 |
* component must be wrapped by {@link org.apache.tapestry.contrib.table.components.TableRows}.
|
|
27 |
* <p>
|
|
28 |
* The component iterates over the columns in the table and automatically renders the column values
|
|
29 |
* for the current table row. The columns are wrapped in 'td' tags by default. <br>
|
|
30 |
* The column values are rendered using the renderer returned by the getValueRenderer() method in
|
|
31 |
* {@link org.apache.tapestry.contrib.table.model.ITableColumn}.
|

32 |
* <p>
|
