Complicated answer, coming up. First, you need to be able to display custom html for a column of your table. This is relatively simple to do, but not exactly obvious. If you have a column called 'delete', then the table component will normally look for a 'delete' property of the object representing a row, and will render the value returned by that property in the table. You can override this behaviour by creating a @Block component within the table declaration in your html. The Block must have the name 'deleteColumnValue' for a 'delete' column, or 'somePropertyColumnValue' for a 'someProperty' column. Within the Block, you can put whatever html you like, including other tapestry components, and that html will be rendered within the column. This will allow you to create html which renders a checkbox. Ideally, your row object has a boolean property (called 'delete' in my example) which you can map directly to your checkbox. Then, when the form is submitted, you can check which rows have the delete property set to true and delete those rows. Of course, when I attempted this, I got very weird behaviour from the table component. I was using a primary key converter to represent each row, but when the form was submitted, the primary keys weren't being converted back into row objects becuase my primary key convertor wasn't being called. I still don't know why. I modified the behaviour of my code so that the delete column rendered a button, and it is now only possible to delete a single row at a time, by pushing the button. I attach the primary key as a paramater to the button listener, so I can just issue SQL (or HQL) to delete the row in question. Take a look at the TapestryTables.war file which contains 9 or 10 table tutorials that cover most of this material pretty well. Just google for 'TapestryTables.war'
