Is there any approach to specify the backgroundColor only for single active cell?

[6axter82]

Hi,
I would like to set the active cell's background colour. Didn't manage to.

Setting the onBlur and onFocus calls only onBlur. onFocus is not called at all. But still, after managing this and setting the colour, all the cells are coloured. I want it to be only for the active cell.

Any suggestions
