You might try our JXTable at

http://xframe.sourceforge.net/swing/jxtable.html




This OpenSource class is an easy to use replacement for the JTable class with additional functionality like

- frozen columns (fixed non-scrollable columns)

- column headers with column groups

- intuitive navigation: nice actions for arrow/tab/pos1/end keys

- configurable layout

- easy adding rows or columns or column groups




There are two sample applets available demonstrating the functionality:

(We recommend JDK 1.4 for all functionalities)

You want the ability to freeze columns. I have implemented that in some of my JTables. However, I implement it with a trick of putting another JTable in the left margin of the scroll pane of the main JTable. This works seamlessly and you can't tell there are really two JTables side by side. It does lead to a few issues, most of which are easily solvable. The trick is that both JTables share the same TableModel but have different TableColumnModels.

JTable mainTable = new JTable(tableModel);
//Share table model
JTable frozenTable = new JTable(tableModel);
TableColumnModel frozenTCM = frozenTable.getColumnModel();
//Empty all columns in frozen table until they are frozen
while(frozenTCM.getColumnCount > 0)
  frozenTCM.removeColumn(frozenTCM.getColumn(0);
//Share selection model
frozenTable.setSelectionModel(mainTable.getSelectionModel());
//Create scrollpane for both tables
JScrollPane sp = new JScrollPane(mainTable);
//Put table for frozen columns in the left margin of scroll pane
sp.setRowHeaderView(frozenTable);
//Put frozen column headers in corner of scroll pane
sp.setCorner(JScrollPane.UPPER_LEFT_CORNER,frozenTable.getTableHeader());

To freeze a column, just get and remove the column from the mainTable's TableColumnModel and add it to the frozenTable's TableColumnModel
