TextArea in Table

Question

Hi!
I am trying to include a textArea as one of the cells in a JTable.
I tried doing this:
public class MyCellRen extends JTextArea implements TableCellRenderer
MyCellRen()
super();
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column)
setText((value == null) ? "" : value.toString());
return this;
but still when I run it , it doesnt show me the TextArea, and when I clcik it it doesnt let me do anything.
I probably think its cos' I havent created a CellEditor for the TextArea for that cell, but atelast the ren should work.
Am I doing something wrong?
Any ideas?
thanks iin advance

I solved this problem by placing the JTextArea into a JPanel
controlled by GridBagLayout. This appears to correct the
results returned by getPreferrredSize().
public class MultiLineCellRndrr extends DefaultTableCellRenderer
public MultiLineCellRndrr ()
this.myText = new JTextArea();
this.myText.setLineWrap(true);
this.myText.setWrapStyleWord(true);
this.myText.setOpaque(true);
this.myText.setEditable(false);
* Gets the text area component for a cell
* @param table
* The parent table.
* @param value
* The cell value.
* @param isSelected
* Is the cell selected?
* @param hasFocus
* Does the cell have focus?
* @param row
* Current row being rendered.
* @param col
* Current column being rendered.
* @return
* The text area component.
public Component
getTableCellRendererComponent ( JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int col )
JPanel panel = new JPanel ();
panel.setLayout (new GridBagLayout());
panel.add (this.myText,
new GridBagConstraints(0, 0, 1, 1, 1.0, 1.0,
GridBagConstraints.CENTER,
GridBagConstraints.BOTH,
new Insets(0, 3, 3, 0), 0, 0));
if (isSelected)
this.myText.setForeground(table.getSelectionForeground());
this.myText.setBackground(table.getSelectionBackground());
else
this.myText.setForeground(table.getForeground());
this.myText.setBackground(table.getBackground());
this.myText.setText(value==null?"":(String)value);
int tableRowHeight = table.getRowHeight(row);
// if the current height is different, resize the row height
if ( (tableRowHeight < panel.getPreferredSize().getHeight() ) )
table.setRowHeight(row, (int)(panel.getPreferredSize().getHeight()));
return panel;

JTextArea myText;
} // end class MultiLineCellRndrr
