I am wondering is there any way to add unique attributes to layout cells?
I need to style some table cells.

You can use dorect string (but pay attention that this approach isn’t public):

layout.cells("b").firstChild.childNodes[1].style.backgroundColor = "#00CED1";

Or you can set an id to the layout cell

dhxLayout.cells("a").id = "cell_A";
