| /** |
| * A <code>TableColumn</code> represents all the attributes of a column in a |
| * <code>JTable</code>, such as width, resizability, minimum and maximum width. |
| * In addition, the <code>TableColumn</code> provides slots for a renderer and |
| * an editor that can be used to display and edit the values in this column. |
| * <p> |
| * It is also possible to specify renderers and editors on a per type basis |
| * rather than a per column basis - see the |
| * <code>setDefaultRenderer</code> method in the <code>JTable</code> class. |
| * This default mechanism is only used when the renderer (or |
| * editor) in the <code>TableColumn</code> is <code>null</code>. |
| * <p> |
| * The <code>TableColumn</code> stores the link between the columns in the |
| * <code>JTable</code> and the columns in the <code>TableModel</code>. |
| * The <code>modelIndex</code> is the column in the |
| * <code>TableModel</code>, which will be queried for the data values for the |
| * cells in this column. As the column moves around in the view this |
| * <code>modelIndex</code> does not change. |
| * <p> |
| * <b>Note:</b> Some implementations may assume that all |
| * <code>TableColumnModel</code>s are unique, therefore we would |
| * recommend that the same <code>TableColumn</code> instance |
| * not be added more than once to a <code>TableColumnModel</code>. |
| * To show <code>TableColumn</code>s with the same column of |
| * data from the model, create a new instance with the same |
| * <code>modelIndex</code>. |
| * <p> |
| * <strong>Warning:</strong> |
| * Serialized objects of this class will not be compatible with |
| * future Swing releases. The current serialization support is |
| * appropriate for short term storage or RMI between applications running |
| * the same version of Swing. As of 1.4, support for long term storage |
| * of all JavaBeans™ |
| * has been added to the <code>java.beans</code> package. |
| * Please see {@link java.beans.XMLEncoder}. |
