extjs change grid cell background based on value

Question

I applied a renderer to my grid-column, but the background color is not changing:

renderer: function(value, meta) {
    if (parseInt(value) > 0) {
                


        

Answer 1

Try

.x-grid-cell.category-matching {
    background-color:green;
}
.x-grid-cell.category-not-matching {
    background-color:red;
}
