Specifying Fixed JTable Columns
Now that you've seen the basics of how the
TableModel
and
AbstractTableModel
describe the
data, you can create a
JTable
with some columns that are fixed columns and some that are not.
To create columns that don't scroll, you need to place a second table in the row header view of
the
JScrollPane
. Then when the user scrolls the table vertically, the two tables will remain in
sync. The two tables then need to share their
ListSelectionModel
. That way, when a row in one
table is selected, the row in the other table will automatically be selected. Figure 18-9 shows a
table with one fixed column and four scrolling columns.

Fixed-column JTable
The source code used to generate Figure 18-9 is shown in Listing 18-4.
