Inserting a Column in a JTable Component</h3>
There is no insertColumn method like
<code>DefaultTableModel.insertRow()</code> for inserting rows. In order to
insert a column at a particular position, you must append the column
using <code>DefaultTable.addColumn()</code> and then move the new column into
the desired position.
See <a href="../javax.swing.table/AppendCol.html" class="eglink"><font size="-1"><b>e919</b> Appending a Column to a JTable Component</font></a> and
<a href="../javax.swing.table/MoveCol.html" class="eglink"><font size="-1"><b>e922</b> Moving a Column in a JTable Component</font></a> for more information.
<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);
// Disable autoCreateColumnsFromModel
table.setAutoCreateColumnsFromModel(false);
// Add data
// Insert a new column at position 2 (becomes 3rd column)
insertColumn(table, <font color="#0066ff"><i>"New Column"</i></font>, null, <font color="#0066ff"><i>2</i></font>);
// Insert a new column at the end
insertColumn(table, <font color="#0066ff"><i>"New Column"</i></font>, null, <font color="#0066ff"><i>table.getColumnCount()</i></font>);
// Creates a new column at position vColIndex
public void insertColumn(JTable table, Object headerLabel,
Object[] values, int vColIndex) {
// This method is defined in
// <a href="../javax.swing.table/AppendCol.html" class="eglink"><font size="-1"><b>e919</b> Appending a Column to a JTable Component</font></a>
betterAddColumn(table, headerLabel, values);
table.moveColumn(table.getColumnCount()-1, vColIndex);
}
