| To this point, we've used only output components in table columns, but you can place any JSF component in a table column. Figure 5-4 shows an application that uses a variety of components in a table. Figure 5-4. JSF Components in Table Cells 
h:dataTable iterates over data, so the table shown in Figure 5-4 provides a list of integers for that purpose; the current integer populates components in the Number, Textfields, Buttons, and Menu columns. Components in a table are no different from components outside tables; you can manipulate them in any manner you desire, including conditional rendering with the rendered attribute, handling events, and the like. The directory structure for the application shown in Figure 5-4 is shown in Figure 5-5. The JSF page, faces configuration file and property resource bundle are given in Listing 5-8 through Listing 5-10.
