Adding rows or columns is really about working with the javax.swing.table.TableModel:

http://java.sun.com/docs/books/tutorial/uiswing/components/table.html

If you are working with a DefaultTableModel, it has methods addRow and andColumn:

e.g

Create two buttons inside the Table ( "Add New Row" ) and ("Add new Column")

their handlers are:

add new row:

//i supose u already have

DefaultTabelModel tablemodel = new DefaultTableModel(rowdata, columnNames);

//and

JTabel jtable = new JTable(tablemodel);

// Handler (row)

jbtAddRow.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e) {

if(jtable.getSelectedRow() >= 0 )

tablemodel.insertRow(jtable.getSelectedRow(), new java.util.Vector());

else

tablemodel.addRow(new java.util.Vector());

}

});

to add new columns its the same but inside actionPerformed method:

ask for e.g "Whats the name for the new column"

then,

tablemodel.addColumn(nameOfColumn, new java.util.Vector());
