Answer 1

The tutorial you linked to has an example: http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#data . You should be able to adapt it to a List<Employee> easily:

public int getRowCount() { 
    return list.size();
}

public int getColumnCount() {
    return 5; 
}

public Object getValueAt(int row, int col) {
    Employee employee = list.get(row);
    if (col == 0) {
        return e.getName();
    }
    else if (col == 1) {
        return e.getGrade();
    }
    ...
}

Answer 2

Using vector should help you. Load an array to a Java table .

Vector model = new Vector();
Vector row = new Vector();

row.add("abce");
row.add("def");
row.add("ghi");
model.add(row);

row = new Vector();
row.add("sds");
row.add("sdfds");
row.add("24");
model.add(row);

JTable table = new JTable(model);

All the methods of Vector is synchronized. But, the methods of ArrayList is not synchronized.
