Adding JButton to cell in JTable

Hi i am trying to add JButton to a cell in JTable.

In the table rows are constant and columns are dynamic.

I have to add JButton only to 4th row in each column.

In remaining columns(like in row 1,2, and 3) i have to enter new values. But its not accepting new values.

I have added cellrenderer and celleditor to each cell.

wht to do plz help me.
