Disabling Selections in a JTable Component</h3>
The only way to completely prevent a selection in a <code>JTable</code>
component is to prevent it from getting the focus using
<code>setFocusable(false)</code>. However, if you need keystrokes to still
work in the component, this method is not an option.
<P> The next closest way to disable selections is to call
<code>setCellSelectionEnabled(false)</code>. After this call,
<code>isCellSelected()</code> correctly returns false for every cell.
However, <code>getSelectedRows()</code> and <code>getSelectedColumns()</code> does not
return empty arrays as expected. Instead, the anchor cell
(<a href="../javax.swing.table/GetAnchor.html" class="eglink"><font size="-1"><b>e943</b> Getting the Anchor Cell in a JTable Component</font></a>) will be considered selected.
Therefore, if you are using these methods, make sure you ignore the
results if <code>getCellSelectionEnabled()</code> returns false.
<pre>
int rows = <font color="#0066ff"><i>10</i></font>;
int cols = <font color="#0066ff"><i>5</i></font>;
JTable table = new JTable(rows, cols);
// Do this only if there's no need for the component to have the focus
table.setFocusable(false);
// Partially disables selections (see description above)
table.setCellSelectionEnabled(false);
</pre>
