<h3>e908. Appending a Row to a JTable Component</h3>
To add a row of data to a <code>JTable</code> component, you need to add it to
its table model. A simple implementation of a table model that
supports appending row data is <code>DefaultTableModel</code>. By
default, a table uses a <code>DefaultTableModel</code>.
<pre> DefaultTableModel model = new DefaultTableModel();
JTable table = new JTable(model);
// Create a couple of columns
model.addColumn(<font color="#0066ff"><i>"Col1"</i></font>);
model.addColumn(<font color="#0066ff"><i>"Col2"</i></font>);
// Append a row
model.addRow(new Object[]{<font color="#0066ff"><i>"v1"</i></font>, <font color="#0066ff"><i>"v2"</i></font>});
// there are now 2 rows with 2 columns
// Append a row with fewer values than columns.
// The left-most fields in the new row are populated
// with the supplied values (left-to-right) and fields
// without values are set to null.
model.addRow(new Object[]{<font color="#0066ff"><i>"v1"</i></font>});
// there are now 3 rows with 2 columns
// Append a row with more values than columns.
// The extra values are ignored.
model.addRow(new Object[]{<font color="#0066ff"><i>"v1"</i></font>, <font color="#0066ff"><i>"v2"</i></font>, <font color="#0066ff"><i>"v3"</i></font>});
// there are now 4 rows with 2 columns
</pre>
