There are at least two ways I can think of doing this...

You could merge all the images into a single image and allow the default TableCellRenderer to render the result as normal

Or...

You need to supply your own TableCellRenderer capable of taking the multiple images and displaying them.

Probably the simplest would be to use a JPanel as a base and add a JLabel per image. This would be a rather expensive process (assuming your have a dynamic number of images per cell), as you would need to remove all the labels from the panel and add the new ones for EACH cell.

See Using Custom Renderers for more details.

  • I'm wouldn't going this way, because XxxRanderer is called from every mouse and Key events over visible JTables Rectangle in the JViewport,

  • prepare this image before, put together all images to one and put only one Icon/ImageIcon to XxxTableModel

  • DefaultCellRenderer returns JLabel by default, add proper LayoutManager to JLabel and laid there images, save images to local variable to avoiding any FileIO on runtime
