All Implemented Interfaces:

public class ActionEditorJButton
extends AbstractCellEditor
implements TableCellEditor, UseTableCellEditorAsTableCellRenderer.UseAsRenderer

This class is suited to render a single AbstractAction on multiple row. Usually the action does involve something row-specific, this would mean that you need to provide a separate AbstractAction instance for each row. And each instance must contain all the data it needs to execute it action. Using one instance and updating it upon click does not work because of the random way parts of the table are redrawn. Providing a separate AbstractAction class will work fine with this editor. But this also supports a single instance approach, where the clicked row index is handed over. In the action listener you can use the utility method to fetch a value from the table: private AbstractAction iAddStorageAbstractAction = new AbstractAction(...) { public void actionPerformed(ActionEvent e) { Standversion lStandversion = (Standversion)AbstractActionEditor.getTableModelValue(e, this, COLUMNIDX_STANDVERSION); ... The value must be fetched using TableModel.getValue in order to handle sorting. One practical hint: usually the button is displayed in one column, but you need other data to execute the action. The data in the columns often are not exactly what you need, so additional querying using an alternate key would be needed. But there is no reason why you cannot use negative column indexes (<0) to provide special data that is not shown in the table! The example above does exactly this.
