oreilly java swing : JTable 之Selection Renderer Editor

15.4 Selecting Table Entries

All this, and all we can do is render and edit data in a table. "What about selecting data?" you ask. Yes, we can do that, too. And, as you might expect, the ListSelectionModel (discussed in Chapter 7) drives us through these selections. Unlike most of the other components, however, the two-dimensional JTable has two selection models, one for rows and one for columns.

15.5 Rendering Cells

You can build your own renderers for the cells in your table. By default, you get renderers for Boolean types (JCheckBox for display and editing), ImageIcon types, Number types (right-justified JTextField), and Object types (JTextField). However, you can specify a particular renderer for a class type or for a particular column, or even for a particular cell.

15.6 Editing Cells

In addition to custom renderers, you can also create custom editors for your table cells. (Actually, the basic stuff in this section also applies to the JTree class.) You have several options ranging from straightforward to completely homegrown.
