解决方案

Add a JComboBox by dragging and dropping outside the frame or panel.So that it will be added to OtherComponents in the Navigator View

Add whatever contents you want to add by double clicking the combobox from Navaigator View

Then rightclick on JTable and click TableContents

In the Dialog select Columns Tab(1) and select the column(2) you want to add the combobox to.

Then Click on the button near to the Editor[Ref screenshot (3)]

Then in the editor dialog Choose Custom Code from the dropdown(4)

Then put the following(5)

new DefaultCellEditor(jComboBox1)//jComboBox1 is the variable name of combobox 

Then Click ok and close and make sure you import import javax.swing.DefaultCellEditor; or do a Ctrl+Shift+I to add the necessary imports

After that If you run and click on column 2 you'll get this output
