First, get the table's default selection background color:

Color color = UIManager.getColor("Table.selectionBackground");

Second, override prepareEditor(), as shown in this example, and set the background color of the editor component to match:

@Override
public Component prepareEditor(TableCellEditor editor, int row, int col) {
    Component c = super.prepareEditor(editor, row, col);
    c.setBackground(color);
    return c;
}

Addendum: While technically correct, note that the editor component's color is typically managed by the corresponding UI delegate while active. An unfortunate choice may result in poor contrast and impaired usability. Thorough testing on target Look & Feels is warranted.
