Cómo agregar JComboBoxes únicos a una columna en una JTable (Java)

Estoy intentando agregar JComboBoxes únicos a una columna en una JTable . Sé que es posible agregar un JComboBox a una columna completa usando

 TableColumn col = table.getColumnModel().getColumn(columnNumber); col.setCellEditor(new MyComboBoxEditor(values)); 

pero necesito que cada JComboBox sea ​​diferente y tenga diferentes cadenas dentro. ¿Algunas ideas?

Reemplace el método getCellEditor (…). Por ejemplo;

 import java.awt.*; import java.awt.event.*; import java.util.List; import java.util.ArrayList; import javax.swing.*; import javax.swing.border.*; import javax.swing.table.*; public class TableComboBoxByRow extends JFrame { List editors = new ArrayList(3); public TableComboBoxByRow() { // Create the editors to be used for each row String[] items1 = { "Red", "Blue", "Green" }; JComboBox comboBox1 = new JComboBox( items1 ); DefaultCellEditor dce1 = new DefaultCellEditor( comboBox1 ); editors.add( dce1 ); String[] items2 = { "Circle", "Square", "Triangle" }; JComboBox comboBox2 = new JComboBox( items2 ); DefaultCellEditor dce2 = new DefaultCellEditor( comboBox2 ); editors.add( dce2 ); String[] items3 = { "Apple", "Orange", "Banana" }; JComboBox comboBox3 = new JComboBox( items3 ); DefaultCellEditor dce3 = new DefaultCellEditor( comboBox3 ); editors.add( dce3 ); // Create the table with default data Object[][] data = { {"Color", "Red"}, {"Shape", "Square"}, {"Fruit", "Banana"}, {"Plain", "Text"} }; String[] columnNames = {"Type","Value"}; DefaultTableModel model = new DefaultTableModel(data, columnNames); JTable table = new JTable(model) { // Determine editor to be used by row public TableCellEditor getCellEditor(int row, int column) { int modelColumn = convertColumnIndexToModel( column ); if (modelColumn == 1 && row < 3) return editors.get(row); else return super.getCellEditor(row, column); } }; JScrollPane scrollPane = new JScrollPane( table ); getContentPane().add( scrollPane ); } public static void main(String[] args) { TableComboBoxByRow frame = new TableComboBoxByRow(); frame.setDefaultCloseOperation( EXIT_ON_CLOSE ); frame.pack(); frame.setVisible(true); } } 

Prueba esto:

 ... final Object[] obj = {"test1", "test2", "test3"}; JTable jTable = new JTable(); TableColumn column = jTable.getColumnModel().getColumn(1); column.setCellEditor(new AutoCompletionComboBoxEditor(obj)); ... public static class AutoCompletionComboBoxEditor extends AbstractCellEditor implements TableCellEditor { JComboBox cbx; public AutoCompletionComboBoxEditor(Object[] items) { cbx = new JComboBox(items); } public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) { return cbx; } public Object getCellEditorValue() { return cbx.getSelectedItem(); } } 

intenta decirme el efecto 🙂
