Header tooltips
The source for the customization in Figure 18-12 is shown in Listing 18-13. Unless you
previously set the headers, it's not really necessary to check if the header for a specific column
is
null
first.
Listing 18-13.
Showing Tooltip Text in a Table Header
JLabel headerRenderer = new DefaultTableCellRenderer();
String columnName = table.getModel().getColumnName(0);

headerRenderer.setToolTipText("Wave");
TableColumnModel columnModel = table.getColumnModel();
TableColumn englishColumn = columnModel.getColumn(0);
englishColumn.setHeaderRenderer((TableCellRenderer)headerRenderer);
