Answer 1

Use a CellRenderer to render the two buttons on the column.

The overriden method could look something like this :

@Override
public Component getTableCellRendererComponent(JTable table, Object value,
                       boolean isSelected, boolean hasFocus, int row, int column)
{
    component = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);


     JPanel buttonPanel = new JPanel();

    //create buttons and add to JPanel. 

    //add an action listener to each of the buttons

    //Return this JPanel at the end of the method.

    return buttonPanel;

}

In the actionPerformed() method for the delete button, find the row that you want to delete. You have the table object. From the table object you can then get the model object. In your model object you should have a method like, getRowForRowNumber(..), where you can pass in the row paramters.

now once you have a reference to your row after clicking the button you just need to go to the backend, update your delete action, remove it from the model, and perform a fireTableDataChanged().
