    Removing a Row from a JTable Component</h3>

To remove a row of data from a <code>JTable</code> component, you need to remove it
from its table model. A simple implementation of a table model that
supports the removal of row data is <code>DefaultTableModel</code>.

<P> When removing a row using <code>DefaultTableModel.removeRow()</code>, the
index of the row must be specified. Row indices start from 0.  For
example, if there are 2 rows in a table, the index of the first row
is 0 and the index of the second row is 1.
Removing a row at index 0 removes the first row.



<pre>
    DefaultTableModel model = new DefaultTableModel();
    JTable table = new JTable(model);
    
    // Create some data
    model.addColumn(<font color="#0066ff"><i>"Col1"</i></font>);
    model.addRow(new Object[]{<font color="#0066ff"><i>"r1"</i></font>});
    model.addRow(new Object[]{<font color="#0066ff"><i>"r2"</i></font>});
    model.addRow(new Object[]{<font color="#0066ff"><i>"r3"</i></font>});
    
    // Remove the first row
    model.removeRow(0);
    
    // Remove the last row
    model.removeRow(model.getRowCount()-1);
</pre>
