Answer 1

You could override the methods isCellEditable(...) and setValueAt(...) in your JTable's TableModel to get the effect desired
// Assuming that each element of the array will be false initially
boolean[][] valueSet = new boolean[noRows][noCols];
public boolean isCellEditable(int row, int col) {
  return !valueSet[row][col];
public void setValueAt(Object obj, int row, int col) {
  super.setValueAt(obj, row, col);
  valueSet[row][col] = true;
}
