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

Question

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?

`JLabels` are just component text representations. Can you not just add the text of the labels? — Reimeus, Apr 12 '13 at 14:35
@Reimeus, i would, but I want the background to be coloured. Is there a way of changing the background colour of the JTable cells? — Mike, Apr 12 '13 at 14:36
I'd say to forget adding the `JLabels`, add the text and use a `TableCellRenderer`. Have a look at _[Editors & Renderers](http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#editrender)_ — Reimeus, Apr 12 '13 at 14:40

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

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;
}
}
