Tables - The Definitive Guide to Java Swing - page 703

TableColumn Properties
Table 18-10 lists the 12 properties of the TableColumn . These properties allow you to customize a
column beyond the initial set of constructor arguments. Most of the time, everything is config-
ured for you based on the TableModel . However, you can still customize individual columns
through the TableColumn class. Yes, all the properties are bound, except for the listener list.

■ Note If an identifier isn't specified, the headerValue setting is used instead.

■ Caution If headerRenderer is null , the default header renderer is used by the column:
TableCellRenderer headerRenderer = table.getTableHeader().getDefaultRenderer(); .
The default is not returned by the getHeaderRenderer() method.

Using Icons in Column Headers
By default, the header renderer for a table displays text or HTML. Although you can get multiple
lines of text and images with HTML, there may come a time when you want to display regular
Icon objects within a header, as shown in the example in Figure 18-11. To do this, you must
change the header's renderer. The header renderer is just another TableCellRenderer .
