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

renderer: function (value, metaData) {
    if (parseInt(value) > 0) {
        metaData.tdStyle = 'background-color:#ffaaaa';
    }
    return value
}
