Hi,

I need to freeze first two rows and columns in a large JTable. I found ways to freeze either a row or a column, but not both at the same time.

Can any of you help ?

Found this code which allows freezing a col. Similar method can be used to freeze column

import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JViewport;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.JTableHeader;
import javax.swing.table.TableModel;

public class FrozenTablePane extends JScrollPane{

public FrozenTablePane(JTable table, int colsToFreeze){
super(table);

TableModel model = table.getModel();

//create a frozen model
TableModel frozenModel = new DefaultTableModel(
model.getRowCount(),
colsToFreeze);

//populate the frozen model
for (int i = 0; i < model.getRowCount(); i++) {
for (int j = 0; j < colsToFreeze; j++) {
String value = (String) model.getValueAt(i, j);
frozenModel.setValueAt(value, i, j);
}
}

//create frozen table
JTable frozenTable = new JTable(frozenModel);

//remove the frozen columns from the original table
for (int j = 0; j < colsToFreeze; j++) {
table.removeColumn(table.getColumnModel().getColumn(0));
}
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

//format the frozen table
JTableHeader header = table.getTableHeader();
frozenTable.setBackground(header.getBackground());
frozenTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
frozenTable.setEnabled(false);

//set frozen table as row header view
JViewport viewport = new JViewport();
viewport.setView(frozenTable);
viewport.setPreferredSize(frozenTable.getPreferredSize());
setRowHeaderView(viewport);
setCorner(JScrollPane.UPPER_LEFT_CORNER, frozenTable.getTableHeader());
}
}
