Question

I need to show multiple icons in a single column in JTable. I am using an modified Icon implementation.

Class IconCollection implements Icon {
    Icon[] icons
}

Since it implements Icon interface , I am able to show multiple icons in single column. However I need to assign separate tooltips for each icon. Since JComponent has single setToolTipText() method, it is not possible.

Any suggestions?

Since the JTable has a decent implementation of getTooltipText which delegates to the component of the renderer, you can completely solve this in the renderer.

In the getTableCellRendererComponent method you can return any JComponent. If you would opt for a JPanel containing multiple icon instances with each a correct tooltip (instead of your big icon).
