Multicolumn Listbox highlight only the selected cell

[scmm]

Hi everyone,
I found the attached example in another discussion related to the multicolumn listbox but I could not understand how to highlight only the cell on which I click with the mouse leaving all the others white.
Can someone help me please?
thanks a lot

Cell (-2,-2) mean all cells.

First fill all cells by white, then will selected by color.

Also you need return color of header (row -1)
