title: Create dynamic table to add new entry with button
body: <p>I am trying to build a register, so that when a button is clicked, a new entry appears on a table. Ideally, I am looking to build a table on the left side of the screen, with two rows and new column appears when the button is clicked. I want the table to have a fixed size, but it should be scrollable after a certain amount of entries. So far, I have created and formatted the <code>JButton</code> objects that I want to be clicked for a new entry to appear. I also know that I should use a <code>JTable</code> to pursue this. </p>
  
  <p>How should I go about making this dynamic table?</p>
