Thank you. However, I thought Netbeans would create a new class that extends to TableCellRenderer or DefaultCellEditor when I entered the name of class automatically. It sounds like Netbeans did not give us that options. Example: Netbeans would allow us to create a new action via GUI (menu).
Am I right that there is no way that netbeans could automatically create a new class related to tablecellrenderer or defaultcelleditor based on the object such as combobox or anything else to be inserted into column?
