title: How to set Focus to the first row in a JTable which is inside a JScrollPane
body: <p>I have a <code>JTable</code> inside a <code>JScrollPane</code>. I have put this inside a panel. As soon the panel loads I want the first row in the JTable to get the focus BUT by default the focus goes to the <code>JScrollPane</code> and on pressing tab the focus enters into table's first row.
  I dont want to use <code>setRowSelectionInterval(0,0)</code> and <code>setColumnSelectionInterval(0,0)</code> as my requirement is different from that.</p>
