How to make the JTable cell 's content auto wrap word?

I know the jtable setDefaultRenderer ,the renderer class extends jtextarea can implement "auto wrap word",.But I also want to set the word position in the cell,so I have to make the renderer class extends jtextfield,but can't implement "auto wrap word".

How to implement toset the word position in the cell and auto wrap word in one cell if the words longer than the width of the cell?
