'Fading' colours in HTML tables

I've had a styling idea for a table I'm creating. Is there any way that the background colour in a table cell can be a fading colour. If you don't know what I mean - where one colour merges/fades into another. For example, the top left of the cell is yellow, the bottom right is pink (to pick a stupid example) - and in the middle they merge into a disgusting sort of pinky-yellow.

Does anyone know a way of doing this? I've considered using images but I can't guarantee the size of the cells in the table.

Thanks in advance.
