How do I add a JLabel[] to a JTable?

问题

I have an array of JLabels which I want to add to a JTable. I tried using

 myJTable.add(myJLabelArray);

Hoping it would work, but it doesn't (Obviously, otherwise I wouldn't be here).

Can somebody please help?

回答1:

Using add method is not the way to add components to a JTable. Components should never be added directly to a JTable or its TableModel.

JLabels are just Swing components that render text.

You can use a TableCellRenderer. Have a look at Editors & Renderers

回答2:

You cannot just add myJTable.add(myJLabelArray). As Reimeus pointed out use Renderers

  jTable1.getColumnModel().getColumn(0).setCellRenderer(new Renderer()); //set column1 with jlabel

Your render should extend DefaulttableCellRenderer

 class Renderer extends DefaultTableCellRenderer {
  JLabel lbl = new JLabel();

 //ImageIcon icon = new ImageIcon(getClass().getResource("sample.png"));

 public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
  boolean hasFocus, int row, int column) {
lbl.setText("hello");
//lbl.setIcon(icon);
return lbl;
}
}
