Answer 1

JTextField jtxf=new JTextField();
     private void setColumns() {
TableColumn column = null;
if(this.getRowCount()>0){
for (int i = 0; i < this.getColumnCount(); i++) {
column = this.getColumnModel().getColumn(i);
          DefaultCellEditor dce = new DefaultCellEditor(jtxf);
          column.setCellEditor(dce);
          dce.setClickCountToStart(1);
simply call this method in constructor it will help u
