title: How to clear data from a JTable?
body: <p>I am programming at Netbeans, and I have a jTable in a frame.</p>
  
  <p>In which I load data that occupies a lot of rows, but then i load another table that has a lot less rows. </p>
  
  <p>And when i am running it, and loading the 2nd table, the extra rows that the first table had are still appearing there. And i wish to just see the 2nd table.</p>
  
  <p>I already tried for <code>jTable.removeAll();</code></p>
