The easiest way is using the RGB_TABLE keyword to cglaodct to get the
table out, and the PALETTE keyword in cgimage to display it:
image = cgdemodata(18)
cgwindow
cgloadct, 4, rgb_table=table1
cgloadct, 13, rgb_table=table2
cgimage, image, palette=table1, /window, layout=[2,1,1]
cgimage, image, palette=table2, /addcmd, layout=[2,1,2]
